信息技术.ASN.1编码规则:编码控制符号表示法(ECN)规范

[中文适用范围]： 广泛，可应用于网络通信、数据库管理、软件开发等多个领域。其内容详细描述了编码控制符号的语法、语义及实现方式，为相关技术的开发和应用提供了明确的指导。 ***此介绍可能不准确，请注意参考原文。 [外文原描述]： ISO/IEC 8825-3:2008 defines Encoding Control Notation (ECN): 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 object identifier (OID) internationalized resource identifier type or the relative OID internationalized resource identifier type (see ISO/IEC 8824-1).
