 34 | Introduction
 35 | ============
 36 | 
 37 | Various FIX protocols and standards supply XML schemas. Users should expect a consistent style and versioning mechanism across all FIX Protocol products.
 38 | 
 39 | Authors
 40 | -------
 41 | 
 42 | Provide list of authors of technical standard, their company or organizational affiliation, public email and or telephone number, and role in drafting the standard.

 50 | |                 |                 |             |          |
 51 | 
 52 | Business Requirements
 53 | =====================
 54 | 
 55 | Consistent style
 56 | ----------------
 57 | 
 58 | This proposal is to improve consistency in style across all FIX XML schemas. Also, users should be presented with only one versioning scheme across those products.
 59 | 
 60 | Among the FIX standards that have XML schemas are:
 61 | 
 62 | -   FIX Repository
 63 | 
 64 | -   FIXML
 65 | 
 66 | -   SBE message schema
 67 | 
 68 | -   FIXatdl
 69 | 
 70 | Schema sources
 71 | --------------
 72 | 
 73 | Based on the XML namespace of schema, a developer should be able to locate the XML schema. This need implies a naming convention and a process for publishing schemas. However, users should not expect the FIX Trading Community to serve XML schemas in real-time to operational systems.
 74 | 
 75 | Issues and Discussion Points
 76 | ============================
 77 | 
 78 | Namespace
 79 | ---------
 80 | 
 81 | All FIX products that have an XML namespace should follow a common convention for naming. A common base URI would allow all FIX schemas to be served from a common host, such as GitHub or Confluence.
 82 | 
 83 | Versioning
 84 | ----------
 85 | 
 86 | Users need to know whether they have the current version of a schema, or alternatively, they need to know where to locate a specific historical version.
 87 | 
 88 | Namespace plays a role in versioning. Breaking changes require a new namespace. However, non-breaking enhancements should not require code changes by users.
 89 | 
 90 | Style
 91 | -----
 92 | 
 93 | A consistent style across all FIX schemas will allow users to treat them with common processes. Style includes:
 94 | 
 95 | -   Naming conventions for namepaces, elements and attributes
 96 | 
 97 | -   Standard copyright notice
 98 | 
 99 | References
100 | ==========
101 | | **Reference**                        | **Version** | **Relevance**  | **Normative** |

121 | FIX XML Schema Standard
122 | =======================
123 | 
124 | Namespace convention
125 | --------------------
126 | 
127 | All FIX XML namespaces must be named according to the following pattern:
128 | 
129 | >http://www.fixprotocol.io/yyyy/protocol-name<
130 | 
131 | where
132 | 
133 | `http://www.fixprotocol.io` is literal
134 | 
135 | `yyyy` is the year that a major version was released
136 | 
137 | `protocol-name` is the base name of the schema in lower case
138 | 
139 | ### Namespace qualification
140 | 
141 | The qualification of element and attribute names should be specified as follows:
142 | 
143 | ```xml
144 |  elementFormDefault="qualified" attributeFormDefault="unqualified"
145 | ```
146 | 
147 | The impact of this specification is that that FIX schema elements must be qualified by namespace in XML documents that mix schemas. It makes clear which elements belong to FIX. (Unqualified is the default value for both element and attribute qualification.)
148 | 
149 | ### Namespace not a URL
150 | 
151 | An XML namespace is only guaranteed to be a unique name, not a URL for downloading the schema. Protocol documentation should make this clear. Nevertheless, the URI should point to a web page that tells where to locate schemas of current and historical versions.
152 | 
153 | Schema versioning
154 | -----------------
155 | 
156 | The major version of an XML schema should be the year that it was released. It is used in the namespace name as described above. A benefit of this approach is that it supports an intuitive assessment of current versus outdated versions.
157 | 
158 | Non-breaking minor enhancements should not cause the namespace to change, however. This allows dependent code to continue to interoperate without change.
159 | 
160 | Full versions must be embedded in the version attribute of the <schema> element. This version should correspond to the version of the protocol that it belongs to.
161 | 
162 | FIX version metadata
163 | --------------------
164 | 
165 | Some FIX files, such as Repository and FIXML, are specific to a FIX version. FIX version should be represented by common attributes in all FIX XML schemas. See appendix A for XML schema for version metadata.
166 | 
167 | Copyright and license notice
168 | ----------------------------
169 | 
170 | Copyright and license notices should be embedded in the <schema> element as a <documentation> element.
171 | 
172 | Copyright notice should be of the form:
173 | 
174 | ```xml
175 | © Copyright yyyy FIX Protocol Limited
176 | ```
177 | 
178 | where yyyy is the year of publication
179 | 
180 | Element and attribute naming convention
181 | ---------------------------------------
182 | 
183 | Capitalization of element and attribute names should be lower camel case. That is, the first letter is lower case, and subsequent first letters of words are upper case. For example, “compositeDataType”.

   1 | # Introduction
   2 | 
   3 | The Financial Information Exchange (FIX) Protocol is a message standard developed to facilitate the electronic exchange of information related to securities transactions. It is intended for use between trading partners wishing to automate communications. FIXML is a technical standard for FIX application messages using XML syntax. This document defines the FIXML 1.1 Technical Standard.
   4 | 
   5 | The Technical Specification is split into the following sections:

  19 | ## Background
  20 | 
  21 | The FPL FIXML working group began investigating the XML format in 1998 and published a white paper supporting an evolutionary approach to support the FIX Protocol using an XML format. The working group released an initial version of the FIXML DTDs on January 15th, 1999. There are DTDs based on FIX Protocol versions 4.1, 4.2 and 4.3. A FIXML Schema was established with the release of FIX 4.4. The working group then focused on optimizing and enhancing the use of XML technologies. The FIXML 1.1 Technical Standard is the result of these enhancements to optimizations for FIX messaging and has been available as part of the standard release process since FIX 5.0 SP2 (April 2009).
  22 | 
  23 | ## FIXML Features
  24 | 
  25 | -   FIXML uses the FIX data dictionary and business logic from the FIX Repository.
  26 | 
  27 | -   FIXML is the XML representation and vocabulary for FIX application messages.
  28 | 
  29 | -   FIXML includes FIX application messages and does not include a session layer.
  30 | 
  31 | -   FIXML can be encapsulated within the FIX Session Protocol or within another protocol like, MQ Series, TIBCO, SOAP, etc.
  32 | 
  33 | ## Specification terms
  34 | 
  35 | These key words in this document are to be interpreted as described [in Internet Engineering Task Force RFC 2119](http://www.apps.ietf.org/rfc/rfc2119.html). These terms indicate an absolute requirement for implementations of the standard: "**must**", or "**required**".
  36 | 
  37 | This term indicates an absolute prohibition: "**must not**".
  38 | 
  39 | These terms indicate that a feature is allowed by the standard but not required: "**may**", "**optional**". An implementation that does not provide an optional feature must be prepared to interoperate with one that does.
  40 | 
  41 | These terms give guidance, recommendation or best practices: "**should**" or "**recommended**". A recommended choice among alternatives is described as "**preferred**".
  42 | 
  43 | These terms give guidance that a practice is not recommended: "**should not**" or "**not recommended**".
  44 | 
  45 | ## Document format
  46 | 
  47 | In this document, examples of FIXML will appear with the FIXML root element enclosing elements, attributes and attribute values.
  48 | 
  49 | ```xml
  50 | <FIXML><element attribute="attributeValue"></FIXML>
  51 | ```

  71 | # FIXML Schema Design Rules
  72 | 
  73 | The FIXML schema may be used to validate FIXML messages. The FIXML schema is generated from the FPL Repository. The FIXML schema may be extended to include enhancements and restrictions of the FIX application messaging standard.
  74 | 
  75 | The following design rules support the design objectives for the FIXML Schema and the FIXML instance documents.
  76 | 
  77 | 1.  FIXML naming
  78 |     a.  Use meaningful abbreviations for element and attribute names wherever possible. Use standard abbreviations for common words (e.g., Price = Px, Currency = Ccy, etc.).
  79 |     b.  Field name prefixes that were used in FIX tag=value format for uniqueness shall be removed -- thus creating a contextual abbreviation.
  80 | 2.  The FIXML root element may include version identifiers (see section on version attributes below).
  81 | 3.  The FIXML root element will include a single FIXML message or a batch of FIXML messages (see section on batching FIXML messages below).
  82 | 4.  FIX messages are implemented as an XML element.
  83 |     a.  The FIXML element name is the abbreviated name of the message.
  84 |     b.  The FIXML element is implemented with a complexType unique for each message.
  85 |         i. The message complexType name is a concatenation of the message name and the string `_message_t`.
  86 |         ii. The message complex type is extended by the complexType `Abstract_message_t`.
  87 |         iii. The message complexType includes a group with a sequence consisting of the message elements (see component instances implemented as elements below).
  88 |         iv. The message complexType includes the attributeGroup for the message (see field instances implemented as attributes below).
  89 |     c.  FIXML elements are not generated for messages that are coded in the repository with NotReqXML=1. These messages are generally not application level messages and include session level messages such as Logon(35=A), Logout(35=5), etc.).
  90 | 5.  FIX field instances within a message or a component are implemented as an attribute within an attribute group for the message or component.
  91 |     a.  The FIXML attribute name is the abbreviated name of the field or a separate abbreviated name within a category as coded in the FIX repository.
  92 |     b.  The FIXML attribute Type is implemented as the field simpleType (see FIX fields implemented as a simpleType below).
  93 |     c.  The FIXML attribute Use is set to required or optional based on whether or not the field instance is required within the message or component.
  94 |     d.  The FIXML attributeGroup name is based on concatenation of the message or component name and the string "Attributes" (e.g. AllocationInstructionAttributes for the AllocationInstruction message)
  95 |     e.  The FIXML attribute is not generated for those fields coded as NotReqXML="1". These fields are generally those that are needed in the Tag=value syntax and not needed in FIXML (e.g. fields that are coded with the NumInGroup data type).
  96 | 6.  FIX component instances within a message or another component are implemented as an XML element in a sequence of elements for the message or parent component.
  97 |     a.  The FIXML component instance element name is the abbreviated name of the FIX component.
  98 |     b.  The FIXML component instance element type is implemented as the component complexType (see FIXML components implemented as a complexType below).
  99 |     c.  The FIXML component instance element minOccurs="1" for components coded as required and minOccurs="0" for components coded as not required in the FIX repository.
 100 |     d.  The FIXML component instance element maxOccurs="1" for components with the type of Block (or ImplicitBlock) in the FIX repository and maxOccurs="unbounded" for components with the type BlockRepeating (or ImplicitBlockRepeating) in the FIX repository.
 101 |     e.  A FIXML component instance element that is coded as inlined in the FIX repository will not be generated. Attributes of this component will be appended to the attributes of the parent component or message. Elements of this inlined component will be appended to the element sequence for the parent component or message.
 102 |     f.  The FIXML elements for components are not generated for components that are coded in the repository with NotReqXML=1. The StandardTrailer component is an example of a component that is not generated in FIXML.
 103 | 7.  FIX components are implemented as a complexType.
 104 |     a.  The FIXML complexType name is a concatenation of the FIX component name and the string `_Block_t`.
 105 |     b.  The FIXML component complexType includes a group with a sequence consisting of the component elements. The name of the group is a concatenation of the component name and the string "Elements".
 106 |     c.  The FIXML component complexType includes an attributeGroup. The attributeGroup name is a concatenation of the component name with the string ""Attributes".
 107 | 8.  FIX fields are implemented as a simpleType.
 108 |     a.  The FIXML field simpleType name is a concatenation of the FIX field name and the string `_t` (e.g. `Account_t`).
 109 |     b.  The FIXML field simpleType is restricted by the FIX field data type or in the case of an enumerated field, by the FIXML field enumeration simpleType (see FIX field enumerations implemented as a simpleType below).
 110 |     c.  The FIXML field simpleType includes the FIX field description as documentation.
 111 |     d.  The FIXML field simpleType includes the FIX field name, component type tag, data type and abbreviated name as application information to cross reference.
 112 | 9.  FIX field enumerations are implemented as a simpleType.
 113 |     a.  The FIXML field enumeration simpleType name is a concatenation of the field name and the string `_enum_t` (e.g. `AdvSide_enum_t`).
 114 |     b.  The FIXML field enumeration simpleType is restricted by the FIX field data type.
 115 |     c.  The FIXML field enumeration simpleType includes the enumeration values for the FIX field.
 116 |     d.  The FIXML field enumeration simpleType includes the enumeration descriptions for each FIX field enumeration value.
 117 | 10. FIX Categories are used to organize FIXML schema files.
 118 |     a.  The FIXML file name
 119 |     b.  Categories coded with NotReqXML=1 are not used in FIXML schema generation (e.g. Session category).
 120 |     c.  FIX Category Sections are used to generate the pre-trade, trade, post-trade and infrastructure FIXML schema files.
 121 | 11. FIX datatypes are mapped to the closest XML Schema datatype whenever possible, thus making FIXML more compatible with standard XML toolsets.
 122 | 12. The complex type `Abstract_message_t` includes the attributes and elements of the StandardHeader component.
 123 | 
 124 | # FIXML Schema Implementation
 125 | 
 126 | Organization of files is driven largely by the requirement to support customization of the FIXML Schema. The basic organization of the schema has the datatypes used by the fields maintained in a separate file. FIX fields are defined in the shared file. Components and the FIXML root element are defined in the component files. FIXML messages are defined within separate category files. Convenience files include the category files and the main file includes the convenience files. The figure below illustrates the relationship of these file types.
 127 | 
 128 | ![](media/FIXML-Schema-Layers.png)
 129 | 
 130 | ##  Extensibility Design Pattern
 131 | 
 132 | An extensibility design pattern is implemented in the FIXML schema that defines how the FIXML definition is partitioned and organized within separate schema files in order to provide a uniform method to support customization.
 133 | 
 134 | The figure below illustrates the relationship between the base and implementation files and the general extensibility design pattern.
 135 | 
 136 | ![](media/FIXML-Schema-Extension.png)
 137 | 
 138 | Each level of schema file (with the exception of datatypes and convenience files) includes a base definition file that defines the standard (default) FIXML language. Each level also includes an implementation (impl) file that references the base definition.
 139 | 
 140 | The figure below illustrates how the design pattern is applied to the various layers of schema files.
 141 | 
 142 | ![](media/FIXML-Schema-File-Hierarchy.png)
 143 | 
 144 | In general, base schema files are intended to be read only and include the FIX standard and implementation files are used to support customization of the base file content.
 145 | 
 146 | The figure below illustrates the read only and customizable files within the FIXML schema hierarchy.
 147 | 
 148 | ![](media/FIXML-Customizable-Schema.png)
 149 | 
 150 | ## FIXML Schema file naming conventions
 151 | 
 152 | As described above, the FIXML schema includes several files. The file naming convention is as follows:
 153 | 
 154 | fixml-*Type*-{base\|impl}-*Version*.xsd
 155 | 
 156 | *Type* is one of:
 157 | 
 158 | - <*category*> - where category is in general one of the FIX message categories (e.g. "multilegorders" for category "MultilegOrders"), exceptions as follows:
 159 |     - "newsevents" for category "EventCommunication"
 160 |     - "indications" for category "Indication"
 161 |     - "order" for category "SingleGeneralOrderHandling"
 162 |     - "listorders" for category "ProgramTrading"
 163 |     - omission of "date" or "referencedata", e.g. "partiesreference" for category "PartiesReferenceData"
 164 |     - omission of "management", e.g. "collateral" for category "CollateralManagement"
 165 | - "components"
 166 | - "datatypes"
 167 | - "fields"
 168 | - "main"
 169 | - "metadata"
 170 | 
 171 | *Version* is the FIX application level version (e.g. "5-0-SP2")
 172 | 
 173 | **Examples**
 174 |     <!-- formats as source code due to 4 spaces of indentation, next line must be empty -->
 175 | 
 176 |     fixml-components-base-5-0-SP2.xml
 177 |     fixml-components-impl-5-0-SP2.xml
 178 |     fixml-datatypes-5-0-SP2.xml
 179 |     fixml-main-5-0-SP2.xml
 180 |     fixml-metadata-5-0-SP2.xml
 181 |     fixml-order-base-5-0-SP2.xml
 182 |     fixml-order-impl-5-0-SP2.xml
 183 | 
 184 | The type of the schema file is identified in the second component of the file name. The datatypes file contains the basic datatypes used within FIXML. The shared files contain the definitions for FIX fields. The components file contains definitions for FIXML components, additional components identified while defining the FIXML schema, and the outer elements for FIX.
 185 | 
 186 | Several FIXML schema files are either a base file or an implementation (impl). Base files define the standard FIXML language. Impl files are used to extend or restrict the base FIXML language.
 187 | 
 188 | Refer to the FIXML Schema File Summary section for a complete list of schema files used in FIXML.
 189 | 
 190 | # FIXML Root Element
 191 | 
 192 | The FIXML root element is used to support versioning requirements and the ability to batch messages.
 193 | 
 194 | ## FIXML Versioning Attributes
 195 | 
 196 | The FIXML root element `<FIXML>` includes several optional attributes that can be used to identify the application and FIXML version details. The FIXML root element is defined in the `fixml-components-base-5-0-SP2.xsd` schema file. The table below illustrates the root level version attributes.
 197 |

 211 | 
 212 | ```xml
 213 | <FIXML v="FIX.5.0SP2" xv="192" s="2014-05-07"> ... </FIXML>
 214 | ```
 215 | 
 216 | ## Batching FIXML messages
 217 | 
 218 | The FIXML root element `<FIXML>` supports the ability to include either a single or a batch of FIXML application messages. Batch capability is provided to support groups of messages, such as post trade confirms or position reports at the end of a trading session.
 219 | 
 220 | ### Batching Structure
 221 | 
 222 | The entity relationship diagram below illustrates the message batching elements and design.
 223 | 
 224 | ![](media/FIXML-Message-Batching.png)
 225 | 
 226 | The figure below illustrates the high level FIXML structure for a single FIX message compared to a batch of FIX messages. For greater detail, refer to the detailed examples included later in this document.
 227 | 
 228 | ![](media/FIXML-Single-versus-Batching.png)
 229 | 
 230 | ### Batch Attributes
 231 | 
 232 | The capability to indicate several optional batch attributes was added in FIX 5.0 SP2 EP128. These additional batch attributes include:
 233 | 
 234 | -   BatchID(50000) `@ID` (String)
 235 | 
 236 | -   BatchProcessMode(50001) `@ProcMode` (int)
 237 | 
 238 | -   BatchTotalMessages(50002) `@TotMsg` (int)
 239 | 
 240 | `@ID` is a unique identifier for a batch of messages.
 241 | 
 242 | `@ProcMode` indicates the processing mode for a batch of messages:
 243 | 
 244 | Valid values include:
 245 | 
 246 | 0 -- Incremental update (default if not specified)
 247 | 
 248 | 1 -- Snapshot (The batch of messages is a complete set)
 249 | 
 250 | `@TotMsg` indicates the total number of messages in the batch.
 251 | 
 252 | ## FIXML Single Message Example
 253 | 
 254 | This example is a FIX NewOrderSingle(35=D) message sent individually in FIXML.
 255 | 
 256 | ```xml
 257 | <FIXML v="FIX.5.0SP2" xv="192" s="2014-05-07">
 258 |     <Order ID="123456" Side="2" TxnTm="2001-09-11T09:30:47-05:00" Typ="2" Px="93.25" Acct="26522154">
 259 |         <Instrmt Sym="IBM" ID="459200101" Src="1"/>
 260 |         <OrdQty Qty="1000"/>
 261 |     </Order>
 262 | </FIXML>
 263 | ```
 264 | 
 265 | ## FIXML Batch Message Example
 266 | 
 267 | This example shows a batch of position reports.
 268 | 
 269 | Note that the header is provided for the entire batch of messages. The batch attribute `@TotMsg` is an optional batch attribute indicating the number of messages included in the batch.
 270 | 
 271 | ```xml
 272 | <FIXML v="FIX.5.0SP2" xv="192" s="2014-05-07">
 273 |     <Batch ID="11212" TotMsg="3">

 315 | # FIXML Datatypes
 316 | 
 317 | The fixml-datatypes-5-0-SP2.xsd schema file contains definitions for the FIXML datatypes. Many of the XML Schema standards are based upon ISO standard datatypes. This means that the FIX representation of UTCTimestamp is different from the FIXML representation. The requirement for conversion between FIX tag=value datatypes and XML is left to implementers.
 318 | 
 319 | FIX data types are mapped to the closest XML schema data type whenever possible. The table below lists the FIX data types, the base data type and the FIXML implementation.

 365 | FIX 5.0 introduced pattern datatypes that are used to appropriately support customization of enumerations and also to support types that require both enumerations and specific patterns, such as the SettlType(63) field. The `<xs:union>` element is used to combine an enumerated type with a pattern type in the `fixml-fields-impl-5-0-SP2.xsd` file.
 366 | 
 367 | The following patterns support validation of user defined enumeration values and extended patterns.

 387 | # FIXML Fields
 388 | 
 389 | FIXML fields are defined in the base and impl files:
 390 | 
 391 | -   Fields base file (`fixml-fields-base-5-0-SP2.xsd`)
 392 | 
 393 | -   Fields implementation file (`fixml-fields-impl-5-0-SP2.xsd`)
 394 | 
 395 | ## Fields base file
 396 | 
 397 | The `fixml-fields-base-5-0-SP2.xsd` file contains simple type definitions for all FIX application level fields and session level fields that are used as part of the FIXML header. All fields are defined as simple types. The simple type name is derived from the full FIX field name appended with a `_t`. All fields with enumerations are defined as simple types. The enumeration simple type name is derived from the full FIX field name appended with the string `enum_t`.
 398 | 
 399 | The following is an example of a field definition for the AvgPx(6) field:
 400 | 
 401 | ```xml
 402 | <xs:simpleType name="AvgPx_t">
 403 |     <xs:annotation>
 404 |         <xs:documentation>Calculated average price of all fills on this order.
 405 |         For Fixed Income trades AvgPx(6) is always expressed as percent-of-par, regardless of the PriceType(423) of LastPx(31). I.e., AvgPx(6) will contain an average of percent-of-par values (see LastParPx(669)) for issues traded in Yield, Spread or Discount.</xs:documentation>
 406 |         <xs:appinfo>
 407 |             <fm:Xref Protocol="FIX" name="AvgPx" ComponentType="Field" Tag="6" Type="Price" AbbrName="AvgPx"/>
 408 |         </xs:appinfo>
 409 |     </xs:annotation>
 410 |     <xs:restriction base="Price"/>
 411 |     </xs:simpleType>
 412 | ```
 413 | 
 414 | The following is an example of the CommType(13) enumerated field:
 415 | 
 416 | ```xml
 417 | <xs:simpleType name="CommType_enum_t">
 418 |     <xs:annotation>
 419 |         <xs:documentation>Commission type</xs:documentation>
 420 |         <xs:appinfo>
 421 |             <fm:Xref Protocol="FIX" name="CommType" ComponentType="Field" Tag="13" Type="char" AbbrName="CommTyp"/>
 422 |         </xs:appinfo>
 423 |         <xs:appinfo>
 424 |             <fm:EnumDoc value="1">Per Unit (implying shares, par, currency, etc.)</fm:EnumDoc>
 425 |             <fm:EnumDoc value="2">Percent</fm:EnumDoc>
 426 |             <fm:EnumDoc value="3">Absolute (total monetary amount)</fm:EnumDoc>
 427 |             <fm:EnumDoc value="4">Percentage waived - cash discount (for CIV buy orders)</fm:EnumDoc>
 428 |             <fm:EnumDoc value="5">Percentage waived -= enhanced units (for CIV buy orders)</fm:EnumDoc>
 429 |             <fm:EnumDoc value="6">Points per bond or contract (supply ContractMultiplier(231) in the Instrument component block if the object security is denominated in a size other than the industry default - 1000 par for bonds)</fm:EnumDoc>
 430 |         </xs:appinfo>
 431 |     </xs:annotation>
 432 |     <xs:restriction base="char">
 433 |         <xs:enumeration value="1"/>
 434 |         <xs:enumeration value="2"/>
 435 |         <xs:enumeration value="3"/>
 436 |         <xs:enumeration value="4"/>
 437 |         <xs:enumeration value="5"/>
 438 |         <xs:enumeration value="6"/>
 439 |     </xs:restriction>
 440 | </xs:simpleType>
 441 | ```
 442 | 
 443 | ## Fields implementation file
 444 | 
 445 | In order to support extension and restriction of enumerations, there is a slightly different approach for use of the base and implementation file for these fields. The enumeration simple type is located in the base file and the standard field simple type referencing the enumeration is located in the implementation file. As shown above, the fixml-fields-base -5-0-SP2.xsd file defines each enumerated field as a simple type named `fieldname_enum_t`. This enumerated type is then used to restrict the corresponding field type in the `fixml-fields-impl-5-0-SP2.xsd` schema file named `fieldname_t`. It is this `fieldname_t` type that is referenced in subsequent schema files (`fixml-components-5-0-SP2.xsd` and the message category schema files). This approach is needed to provide a mechanism to extend enumerations. The fieldname\_t can be modified in the `fixml-fields-impl` file to include additional enumerations. The `fieldname_t` can be restricted by redefining the `fieldname_enum_t` simple type within the `fixml-fields-impl-5-0-SP2.xsd` file.
 446 | 
 447 | The following is an example of the FIX standard CommType(13) field definition in the implementation file.
 448 | 
 449 | ```xml
 450 | <xs:simpleType name="CommType_t">
 451 |     <xs:restriction base="CommType_enum_t"/>
 452 | </xs:simpleType>
 453 | ```
 454 | 
 455 | # FIXML Components
 456 | 
 457 | Component FIXML schema files are used to define the Common category reusable components in the FIX application standard. There are two Common components files
 458 | 
 459 | -   `fixml-components-base-5-0-SP2.xsd` -- components base file
 460 | 
 461 | -   `fixml-components-impl-5-0-SP2.xsd` -- components implementation file
 462 | 
 463 | ## Components base file
 464 | 
 465 | The `fixml-components-base-5-0-SP2.xsd` file contains the definitions for all FIX Common category components. The FIXML root element, FIXML headers, the batch element, and the abstract message type are also defined within this file.
 466 | 
 467 | Components (and messages) are defined using element groups and attribute groups. The advantage of these groups is that you can redefine the groups (using either restriction or extension) to change the overall structure of the component (or message).
 468 | 
 469 | These groups are defined for each component.
 470 | 
 471 |   ----------------------------- ---------------------------------------------------------------------------------------------
 472 |   <*componentName*>`Elements`   A group that contains a list of elements contained in the component.
 473 |   <*componentName*>`Attributes` An attribute group that contains a list of Attributes contained in the component.
 474 |   <*componentName*>`_Block_t`   Defines the component with the attributes of the attribute group and the group of elements.
 475 |   ----------------------------- ---------------------------------------------------------------------------------------------
 476 | 
 477 | The Parties Component block is shown below. Notice the overall definition pattern. This pattern is followed for all component blocks and message definitions.
 478 | 
 479 | ```xml
 480 | <xs:group name="PartiesElements">
 481 |     <xs:sequence>
 482 |         <xs:element name="Sub" type="PtysSubGrp_Block_t" minOccurs="0" maxOccurs="unbounded"/>
 483 |     </xs:sequence>
 484 | </xs:group>
 485 | <xs:attributeGroup name="PartiesAttributes">
 486 |     <xs:attribute name="ID" type="PartyID_t" use="optional"/>
 487 |     <xs:attribute name="Src" type="PartyIDSource_t" use="optional"/>
 488 |     <xs:attribute name="R" type="PartyRole_t" use="optional"/>
 489 |     <xs:attribute name="Qual" type="PartyRoleQualifier_t" use="optional"/>
 490 | </xs:attributeGroup>
 491 | <xs:complexType name="Parties_Block_t">
 492 |     <xs:annotation>
 493 |         <xs:appinfo>
 494 |         <fm:Xref Protocol="FIX" name="Parties" ComponentType="BlockRepeating" Category="Common"/>
 495 |         </xs:appinfo>
 496 |     </xs:annotation>
 497 |     <xs:sequence>
 498 |         <xs:group ref="PartiesElements"/>
 499 |     </xs:sequence>
 500 |     <xs:attributeGroup ref="PartiesAttributes"/>
 501 | </xs:complexType>
 502 | ```
 503 | 
 504 | ## Components implementation file
 505 | 
 506 | The `fixml-components-impl-5-0-SP2.xsd` file simply includes the components-base file. This is the file where modifications (restrictions or extensions) would be made to Common components (components not coded to a specific Category) used in the FIX protocol.
 507 | 
 508 | # FIXML Categories
 509 | 
 510 | Each message category defined within the FIX specification has its own pair of schema files (a base and an implementation schema file). This provides a granular level of usage for applications only requiring access to one message category. The message category schema files contain the component and message definitions that belong to a specific message category defined within the FIX Protocol. Examples of message categories include: Indications, Market Data, Positions, Allocation, etc. A complete list of the category files for FIXML is provided in the FIXML Schema File Summary section.
 511 | 
 512 | ## Category base file
 513 | 
 514 | The category base schema file includes the standard FIX components and messages that are coded for the category. Category messages and components are defined following a similar pattern defined above for components. Messages will include an additional element for the abbreviated message name.
 515 | 
 516 | The following is an example of the NewOrderSingle(35=D) message from the `fixml-order-base-5-0-SP2.xsd` FIXML schema file:
 517 | 
 518 | ```xml
 519 | <xs:group name="NewOrderSingleElements">
 520 |     <xs:sequence>
 521 |         <xs:element name="Pty" type="Parties_Block_t" minOccurs="0" maxOccurs="unbounded"/>
 522 |         <xs:element name="TgtPty" type="TargetParties_Block_t" minOccurs="0" maxOccurs="unbounded"/>

 662 | ## Category implementation file
 663 | 
 664 | The category implementation file simply includes the category base file. The implementation file is where modifications (restrictions or extensions) would be made to the category components and messages.
 665 | 
 666 | # FIXML Convenience Files
 667 | 
 668 | Convenience files are provided with the FIXML schema version that includes the message categories for each of the trade life cycles (pre-trade, trade, post-trade) used by FIX. These files are provided to make it easier for applications that require access to multiple message categories within one of the trading life cycles.
 669 | 
 670 | ## Pre-trade file
 671 | 
 672 | `fixml-pretrade-5-0-Sp2.xsd` - Includes the pre-trade message category implementation files.
 673 | 
 674 | ## Trade file
 675 | 
 676 | `fixml-trade-5-0-SP2.xsd` -- Includes the trade message category implementation files.
 677 | 
 678 | ## Post trade file
 679 | 
 680 | `fixml-trade-5-0-SP2.xsd` -- Includes the post trade message category implementation files.
 681 | 
 682 | ## Infrastructure file
 683 | 
 684 | `fixml-infrastructure-5-0-SP2.xsd` -- Includes the infrastructure message category implementation files.
 685 | 
 686 | ## Main file
 687 | 
 688 | `fixml-main-5-0-SP2.xsd` - The main schema file includes the pre-trade, trade, post trade, and infrastructure schema files. This is provided for applications that require access to the full suite of FIX messages.
 689 | 
 690 | # FIXML Customization
 691 | 
 692 | The FIXML schema files have been organized to support extensions. Implementation versions of each schema file (with the exception of the datatypes and main schema files) are provided to permit users to redefine the standard (base) FIXML schema. This section provides guidelines for customizing the FIXML schema files.
 693 | 
 694 | Even though a considerable amount of work has gone into making FIXML extensible, users are strongly encouraged to minimize modifications, in order to promote more consistent usage of the FIXML syntax within the industry. Obviously, the less customization, the easier it is to connect to counterparties.
 695 | 
 696 | If customization is required, you are encouraged to communicate your requirements that are not being met by FIX to the FPL Global Technical Committee. There you may find out that there is a technique to meet your business requirement. Or, you may find that the Technical Committee has already addressed the issue for a planned future release. At a minimum you will receive coaching and assistance in how to extend FIXML in such a way as to make the new feature a part of a future version of FIX.
 697 | 
 698 | ## Defining a custom field
 699 | 
 700 | New fields can be defined as an XML simpleType in the `fixml-fields-impl-5-0-SP2.xsd` schema file. It is recommended to add the field to the end of the schema document. It is also strongly encouraged to include XML comments to define the reason the new field must be added and there is not already a standard FIX field with the same meaning and use.
 701 | 
 702 | The field reference is added to the component or message where it is to be used.
 703 | 
 704 | If the field will be added to a standard message or component contained in a base file, the message or component must be redefined in the correct impl schema file. For Common components, this would be the `fixml-components-impl-5-0-SP2.xsd` file.
 705 | 
 706 | Adding a field reference to a component or message contained in one of the message categories is done using the correct category impl schema file (e.g. `fixml-marketdata-impl-5-0-SP2.xsd`). The component or message must be redefined in the impl schema file.
 707 | 
 708 | It is encouraged to append new enhancements to the end of the schema files.
 709 | 
 710 | ## Restricting enumeration values for a FIX field
 711 | 
 712 | Restricting enumeration values is done by modifying the type definition in the `fixml-fields-impl 5-0-SP2.xsd` schema file.
 713 | 
 714 | ## Extending enumeration values for a FIX field
 715 | 
 716 | Extending enumeration values is done by creating a union of the original enumeration type definition with new enumeration values in the `fixml-fields-impl 5-0-SP2.xsd` schema file.
 717 | 
 718 | ## Making an optional field required
 719 | 
 720 | Making an optional field required is done by redefining the optional attribute group, modifying the usage of the field from "optional" to "required". This redefinition is done within the implementation file for either the components for Common components or the implementation file for a particular message category (e.g. `fixml-marketdata-impl-5-0-SP2.xsd`).
 721 | 
 722 | ## Making a required field optional
 723 | 
 724 | It is not possible to make a required field optional without modifying the original required element or attribute group. Making required fields optional does go against the standard base definition of FIX and should be avoided.
 725 | 
 726 | ## Adding a custom message
 727 | 
 728 | Custom messages are added by creating a message structure within the category to which the custom message belongs. Required and optional element and attribute groups should be created for the custom message.
 729 |
