XML Encoding Rules

From Wikipedia, the free encyclopedia

XML Encoding Rules (XER) are a set of ASN.1 encoding rules for producing an XML-based verbose textual transfer syntax for data structures described in ASN.1.

A variant of XER called Canonical XML Encoding Rules (CXER) is also defined for uses where the encodings have to be preserved, such as security exchanges. Data encoded in CXER is always valid XER, but not vice versa.
