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.\u00a0 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.\u00a0 It is implicit in the specification of these encoding rules that they are also used for decoding.<\/p>\n

The encoding rules specified in this document :<\/p>\n

\u2013\u00a0\u00a0\u00a0\u00a0\u00a0 are used at the time of communication;<\/p>\n

\u2013\u00a0\u00a0\u00a0\u00a0\u00a0 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;<\/p>\n

\u2013\u00a0\u00a0\u00a0\u00a0\u00a0 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\u00a08824-1.<\/p>\n

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.<\/p>\n","protected":false},"excerpt":{"rendered":"
