Abstract This documenet describes an IANA maintained registry for IETF standards which use XML related items such as Namespaces, DTD, Schemas, and RDF Schemas. 1. Introduction Over the past few years XML has become a widely used method for data markup. There have already been several IETF Working Groups that have produced standards that define XML DTDs, XML Namespaces and XML Schemas. EAch one of these technologies uses URIs[1] to identify their respective versions. For example, a given XML document defines its DTD using the DOCTYPE element. This element, like SGML, has a PUBLIC and a SYSTEM identifier. It is standard practice within W3C standards to forego the use of the PUBLIC identifier in favor of 'well known' SYSTEM identifiers. There have been several IETF standards that have simply created non-existent URIs in order to Mealling Expires May 18, 2001 [Page 1] Internet-Draft IANA XML Registry November 2000 simply identify but not resolve the SYSTEM identifier for some given XML document. This document seeks to standardize this practice by creating an IANA maintained registry of XML elements so that document authors and implementors have a well maintained and authoritative location for their XML elements. As part of this standard, the IANA will both house the public representation of the document and assign it a Uniform Resource Name that can be used as the URI in any URI based identification components of XML. 2. Registerable Documents 2.1 The Assigned URIs All elements registered in this registry will generate a URN of the form: urn:iana:xml:: where is the type of the document being registered (see below).
