	Status of this Memo
	This document is an Internet-Draft and is in full conformance with
	all provisions of Section 10 of RFC2026.
	Internet-Drafts are working documents of the Internet Engineering
	Task Force (IETF), its areas, and its working groups. Note that
	other groups may also distribute working documents as
	Internet-Drafts.
	Internet-Drafts are draft documents valid for a maximum of six
	months and may be updated, replaced, or obsoleted by other documents
	at any time. It is inappropriate to use Internet-Drafts as reference
	material or to cite them other than as "work in progress."

	Abstract
	This document describes a URN namespace that is engineered by the
	Organization for the Advancement of Structured Information Standards
	(OASIS) for naming persistent resources stored in the XML.org
	repository (such as XML Document Type Definitions, XML Schemas,
	Namespaces, Stylesheets, and other documents).
	1. Introduction
	The XML.org Registry is provided by XML.org as a public service
	where XML schemas, DTDs, stylesheets, and other documents can be
	shared. Documents are submitted to a repository then retrieved by
	others who may want to use them. These documents require unique
	identifiers.
	Motivated by these observations, XML.org would like to assign URNs
	to some resources in order to retain unique, permanent
	location-independent names for them.
	This namespace specification is for a formal namespace.
	2. Specification Template
	Namespace ID:
	"xmlorg" requested.
	Registration Information:
	Registration Version Number: 1
	Registration Date: 2000-12-18
	Declared registrant of the namespace:
	OASIS
	Karl Best
	Declaration of structure:
	The Namespace Specific String (NSS) of all URNs assigned by
	XML.org will have the following hierarchical structure:
	There is one branch at the top of the hierarchy: "objects".
	The Objects Hierarchy
	The general structure of the NSS in the names hierarchy has
	the form:
	urn:xmlorg:objects:{type}{:subtype}?:{object-id}
	where "type" identifies the document type (document, schema,
	stylesheet, entity, xmlns, etc.), the optional "subtype"
	provides additional information about the document type (for
	example, stylesheet or schema language), and "object-id" is a
	unique identifier for the document.
	The Director of Technical Operations at OASIS assigns document
	types, subtypes, and all unique identifiers.
	Relevant ancillary documentation:
	None
	Identifier uniqueness considerations:
	Identifier uniqueness will be enforced by the Director of
	Technical Operations who assigns unique identifiers to all
	documents identified by URN.
	Identifier persistence considerations:
	OASIS is committed to maintaining the accessability and
	persistence of all the resources that are assigned URNs.
	Process of identifier assignment:
	Assignment is limited to the owner and those authorities that
	are specifically designated by the owner. OASIS may assign
	portions of its namespace for assignment by other parties.
	Process of identifier resolution:
	The owner will distribute catalogs (OASIS TR9401 Catalogs)
	that map the assigned URNs to resource identifiers (e.g.,
	URLs). In addition, the owner may provide an online resolution
	service based on RFC2483.
	The owner will authorize additional resolution services as
	appropriate.
	Rules for Lexical Equivalence:
	URNs are lexically equivalent if they are lexically identical.
	Conformance with URN Syntax:
	No special considerations.
	Validation mechanism:
	None specified. The owner will publish OASIS TR9401 Catalogs.
	The presence of a URN in a catalog indicates that it is valid.
	Scope:
	Global
	3. Examples
	The following examples are not guaranteed to be real. They are
	listed for pedagogical reasons only.
	urn:xmlorg:objects:schema:xmlschema:xcatalog
	urn:xmlorg:objects:dtd:xml:docbook:v4.1.2
	4. Security Considerations
	There are no additional security considerations other than those
	normally associated with the use and resolution of URNs in general.
