Information Technology — Abstract Syntax Notation One (ASN.1) — Part 3: Constraint Specification 1 Scope This part of GB/T 16262 is part of Abstract Syntax Notation One (ASN.1) and provides notation for specifying user-defined constraints, table constraints, and contents constraints. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of GB/T 16262. For dated references, subsequent amendments (excluding corrections), or revisions, of any of these publications do not apply to this part. However, parties to agreements based on this part are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.
