NBN ISO/IEC 8825-2:2021

This Recommendation | International Standard specifies a set of Packed Encoding Rules that may be used to derive a
transfer syntax for values of types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1. These Packed Encoding Rules are also
to be applied for decoding such a transfer syntax in order to identify the data values being transferred.
The encoding rules specified in this Recommendation | International Standard:
– are used at the time of communication;
– are intended for use in circumstances where minimizing the size of the representation of values is the major
concern in the choice of encoding rules;
– allow the extension of an abstract syntax by addition of extra values, preserving the encodings
of the existing values, for all forms of extension described in Rec. ITU-T X.680 | ISO/IEC 8824-1;
– can be modified in accordance with the provisions of Rec. ITU-T X.695 | ISO/IEC 8825-6.
