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:
“The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.”
—John Locke (1632–1704)
