| IETF XML Registry
IETF XML Registry [RFC3688] defines an IANA maintained registry of XML documents used within IETF protocols. These documents are divided into classes: XML Namespaces, Document Type Declarations, Schemas, and RDF Schemas. Individual documents are then registered within each class. The class and document names are combined to form a name which is then used within the 'urn:ietf:params:xml' portion of the IANA maintained URN space for protocol parameters. The following is the list of classes: publicid ns schema rdfschema Comments concerning the layout, construction and functionality of this site should be sent to webmaster@iana.org.
