Description: XML Namespaces (XML-NS) provide a simple method for qualifying element and attribute names used in Extensible Markup Language (XML) documents by associating them with namespaces identified by Uniform Resource Identifier (URI) references. In documents conforming to this specification, element and attribute names appear as qualified names, a name defined by XML Namespaces and subject to Namespace interpretation. Declarations of qualified names are scoped by the elements on which they appear so that different bindings may apply in different parts of a document. To adhere to this specification, processors must recognize and act on these different declarations and prefixes.
Technology/Standard Usage Requirements: Users must ensure their use of this technology/standard is consistent with VA policies and standards, including, but not limited to, VA Handbooks 6102 and 6500; VA Directives 6004, 6513, and 6517; and National Institute of Standards and Technology (NIST) standards, including Federal Information Processing Standards (FIPS). Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
