Phạm vi áp dụng / Scope of standard

This Recommendation | International Standard specifies a set of
basic encoding rules that may be used to derive the specification
of a transfer syntax for values of types defined using the notation
specified in ITU-T Rec. X.680 | ISO/IEC 8824-1, ITU-T Rec. X.681 |
ISO/IEC 8824-2, ITU-T Rec. X.682 | ISO/IEC 8824-3, and ITU-T Rec.
X.683 | ISO/IEC 8824-4, collectively referred to as Abstract Syntax
Notation One or ASN.1. These basic encoding rules are also to be
applied for decoding such a transfer syntax in order to identify
the data values being transferred. It also specifies a set of
canonical and distinguished encoding rules that restrict the
encoding of values to just one of the alternatives provided by the
basic encoding rules.
