XML Encoding Rules (XER), defined in ITU-T standard X.693, are a set of ASN.1 encoding rules for producing an XML-based verbose textual transfer syntax for data structures described in ASN.1.
XER allows some flexibility with respect to, for example, white-space characters between XML elements. A variant of XER called Canonical XML Encoding Rules (CXER) is also defined for uses where encodings have to be deterministic, such as security exchanges. Data encoded in CXER is always valid XER, but not vice versa.
Famous quotes containing the word rules:
“In really hard times the rules of the game are altered. The inchoate mass begins to stir. It becomes potent, and when it strikes,... it strikes with incredible emphasis. Those are the rare occasions when a national will emerges from the scattered, specialized, or indifferent blocs of voters who ordinarily elect the politicians. Those are for good or evil the great occasions in a nation’s history.”
—Walter Lippmann (1889–1974)
