Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document is Part 4 of GB/T 16262 "Abstract Syntax Notation for Information Technology One (ASN.1)". GB/T 16262 has been published The following parts.

--- Part 1: Basic notation specification;

--- Part 2: Information object specifications;

--- Part 3: Constraint specifications;

--- Part 4: Parameterization of the ASN.1 specification.

This document replaces GB/T 16262.4-2006 "Information Technology Abstract Syntax Notation One (ASN.1) Part 4: ASN.1 Specification"

Compared with GB/T 16262.4-2006, in addition to structural adjustments and editorial changes, the main technical changes are as follows.

a) Changed the description of the range of "DummyReference" in "ParameterList" (see 8.4, 8.4 of the 2006 edition);

b) The expressions of "parameterized assignment" and "parameterized reference" have been changed (see 8.7, 8.7 of the 2006 edition).

This document is equivalent to ISO /IEC 8824-4:2021 "Information technology Abstract Syntax Notation One (ASN.1) Part 4: ASN.1 Parameterization of specifications".

The following minimal editorial changes were made to this document.

Introduction

GB/T 16262 "Abstract Syntax Notation for Information Technology One (ASN.1)" aims to standardize the abstract syntax notation.

Based on ISO /IEC 8824 (all parts), GB/T 16262 is intended to consist of four parts.

--- Part 1: Basic notation specification. The purpose is to define data types, values and constraints on data types.

--- Part 2: Information object specifications. The purpose is to provide information object categories, information objects and information object sets. Memorization method.

--- Part 3: Constraint specification. The purpose is to provide a notation for specifying user-defined constraints, table constraints and content constraints.

--- Part 4: Parameterization of ASN.1 specifications. The purpose is to define the parameterization notation of ASN.1 specifications.

1 Scope

This document defines the parameterized notation for the ASN.1 specification.
