标准范围

本文档提供了一种称为抽象语法符号One(ASN.1)的标准符号，用于定义数据类型、值和数据类型上的约束。本文件:-定义许多简单类型及其标签，并指定用于引用这些类型和指定这些类型值的符号；-定义用于从更基本的类型构造新类型的机制，并指定用于定义此类类型并为其分配标签以及用于指定这些类型的值的符号；-定义在ASN.1中使用的字符集（通过参考其他建议和/或国际标准）。只要需要定义信息的抽象语法，就可以应用ASN.1符号。ASN.1符号由定义ASN.1类型的编码规则的其他标准引用。

This document provides a standard notation called Abstract Syntax Notation One (ASN.1) that is used for the definition of data types, values, and constraints on data types.
This document:
– defines a number of simple types, with their tags, and specifies a notation for referencing these types and for specifying values of these types;
– defines mechanisms for constructing new types from more basic types, and specifies a notation for defining such types and assigning them tags, and for specifying values of these types;
– defines character sets (by reference to other Recommendations and/or International Standards) for use within ASN.1.
The ASN.1 notation can be applied whenever it is necessary to define the abstract syntax of information.
The ASN.1 notation is referenced by other standards which define encoding rules for the ASN.1 types.
