Information technology - Generic applications of ASN.1: Fast Infoset - Technical Corrigendum 1: January 2015
 N CAN/CSA-ISO/IEC 24824-1:08

Annotation

This Recommendation | International Standard specifies an ASN.1 type (see ITU-T Rec. X.680 | ISO/IEC 8824-1) whose abstract values represent instances of the W3C XML Information Set. It also specifies binary encodings for those values, using ASN.1 Encoding Control Notation (see ITU-T Rec. X.692 | ISO/IEC 8825-3).

NOTE – These encodings are called fast infoset documents.

This Recommendation | International Standard also specifies techniques that:

– minimize the size of fast infoset documents;

– maximize the speed of creating and processing fast infoset documents;

– allow the specification (by the generator of a fast infoset document) of additional processing data.

The first two techniques involve the use of conceptual vocabulary tables. The set of vocabulary tables and the nature of their entries is fully defined in this Recommendation | International Standard, but their representation in computer memory is outside the scope of this Recommendation | International Standard. Provision for transfer or storage of, or a formal notation for displaying or specifying, vocabulary tables to be used as an external vocabulary is also outside the scope of this Recommendation | International Standard.

The third technique involves the provision of additional processing data and a URI that identifies the form and semantics of that data. The specification of specific forms of additional processing data and their use is outside the scope of this Recommendation | International Standard.
