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:
“For 350 years we have been taught that reading maketh a full man, conference a ready man and writing an exact man. Football’s place is to add a patina of character, a deference to the rules and a respect for authority.”
—Walter Wellesley (Red)
