CAN/CSA-ISO/IEC 8825-1B-04 (R2009)

Scope

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.
