Information technology - ASN.1 encoding rules - Part 4: XML Encoding Rules (XER)

PUBLISH DATE 2021
ISO/IEC 8825-4:2021

This document specifies a set of basic XML Encoding Rules (BASIC-XER) that may be used to derive a transfer syntax for values of types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1 and Rec. ITU-T X.681 | ISO/IEC 8824-2.

This document also specifies a set of Canonical XML Encoding Rules (CXER) which provide constraints on the basic XML Encoding Rules and produce a unique encoding for any given ASN.1 value.

This document further specifies a set of extended XML Encoding Rules (EXTENDED-XER) which adds further encoders options, and also allows the ASN.1 specifier to vary the encoding that would be produced by BASIC-XER.

It is implicit in the specification of these encoding rules that they are also used for decoding.

The encoding rules specified in this document:

  • are used at the time of communication;
  • are intended for use in circumstances where displaying of values and/or processing them using commonly available XML tools (such as browsers) is the major concern in the choice of encoding rules;
  • allow the extension of an abstract syntax by addition of extra values for all forms of extensibility described in Rec. ITU-T X.680 | ISO/IEC 8824-1.

This document also specifies the syntax and semantics of XER encoding instructions, and the rules for their assignment and combination.

XER encoding instructions can be used to control the EXTENDED-XER encoding for specific ASN.1 types.
