中文名称：信息技术 ASN.1编码规则 第3部分：编码控制符号（ECN）规范

英文名称：Information technology — ASN.1 encoding rules — Part 3: Specification of Encoding Control Notation (ECN)

标准范围

本文档定义了一种用于指定ASN.1类型或类型部分编码的符号。它为这种规范提供了几种机制，包括:-使用标准化符号直接指定编码；-通过参考标准化编码规则来指定编码；-通过参考编码结构来指定ASN.1类型的编码；-使用非ECN符号的编码规范。它还提供了将编码规范链接到要应用它们的类型定义的方法。ECN目前不提供对使用OID国际化资源标识符类型或相关OID国际化资源标识符类型的规范的任何支持(参见Rec.ITU-T X.680 ISO/IEC 8824-1)，并且在本标准中不再进一步提及这些。

This document defines a notation for specifying encodings of ASN.1 types or of parts of types.
It provides several mechanisms for such specification, including:
– direct specification of the encoding using standardized notation;
– specification of the encoding by reference to standardized encoding rules;
– specification of the encoding of an ASN.1 type by reference to an encoding structure;
– specification of the encoding using non-ECN notation.
It also provides the means to link the specification of encodings to the type definitions to which they are to be applied.
ECN does not currently provide any support for specifications using the OID internationalized resource identifier type or the relative OID internationalized resource identifier type (see Rec. ITU-T X.680 | ISO/IEC 8824-1), and these are not referred to further in this Standard.
