信息技术.ASN.1编码规则:将W3C XML模式定义映射到ASN.1

[中文适用范围]： 包括但不限于网络通信、数据交换、系统集成等领域，为相关技术的开发和应用提供了基础支持。 ***此介绍可能不准确，请注意参考原文。 [外文原描述]： ISO/IEC 8825-5:2008 specifies two Versions of a mapping from any XSD Schema into an ASN.1 schema. The ASN.1 schema for both Versions support the same semantics and validate the same set of XML documents. ISO/IEC 8825-5:2008 specifies the final XER encoding instructions that are to be applied as part of the defined mapping to ASN.1 types, but does not specify which syntactic form is to be used for the specification of those final XER encoding instructions, or the order or manner of their assignment. There are different ways (syntactically) of assigning XER encoding instructions for use in EXTENDED-XER encodings (for example, use of ASN.1 type prefix encoding instructions or use of an XER encoding control section). The choice of these syntactic forms is a matter of style and is outside the scope of ISO/IEC 8825-5:2008.
