Abstract
This document defines a set of Abstract Syntax Notation One (ASN.1)
encoding rules, called the Robust XML Encoding Rules or RXER, that
produce an Extensible Markup Language (XML) representation for values
of any given ASN.1 data type. Rules for producing a canonical RXER
encoding are also defined.
