标准范围

XML是由万维网联盟（W3C）定义的技术标准，可用于标准化ISO 20022消息的物理表示（即语法）。XML为在特定应用程序中使用它的确切方式留下了很大的自由。因此，仅仅说明使用了XML不足以保证可预测性；还必须解释如何使用它。ISO/TS 20022-4:2004包含一组XML设计规则，称为ISO 20022 XML。这些设计规则定义了一条标准化的消息（根据ISO/TS 20022-3的建模指南，由UML中的消息定义描述）必须如何表示为符合ISO 20022的有效XML文档。W3C定义的有效XML文档（称为“XML实例”）是任何具有相关描述且符合该描述中表达的约束的XML文档。本例中的相关描述源自消息定义，消息定义最初是用UML描述的。ISO/TS 20022-4:2004还描述了如何（部分）将UML消息定义转换为W3C XML模式。然后，该XML模式将使使用验证XML模式解析器自动验证给定XML实例是否符合消息定义中描述的约束（一个子集）成为可能。

XML is a technical standard defined by the World Wide Web Consortium (W3C) that can be used for the physical representation (i.e. the syntax) of standardized ISO 20022 Messages. XML leaves a lot of freedom for the exact way it is used in a particular application. Therefore, merely stating that XML is used is not sufficient to guarantee predictability; one must also explain how it will be used.ISO/TS 20022-4:2004 contains a set of XML design rules, called ISO 20022 XML. These design rules define how a standardized Message - described by a Message Definition in UML according to the Modelling Guidelines of ISO/TS 20022-3 - must be represented as a valid ISO 20022 compliant XML document.A valid XML document (referred to as an "XML instance") as defined by W3C is any XML document that has an associated description and that complies with the constraints expressed in that description. The associated description in this case is derived from the Message Definition, which is originally described in UML.ISO/TS 20022-4:2004 also describes how (a part of) the UML Message Definition can be converted into a W3C XML Schema. This XML schema will then make it possible to use a validating XML schema parser to automatically verify that a given XML instance complies with (a subset of) the constraints described in the Message Definition.
