The W3C's XML Core WG is pleased to announce the advancement of the
XML Information Set to Candidate Recommendation status:
XML Information Set
John Cowan, Richard Tobin, eds.
This specification provides a set of definitions for use
in other specifications that need to refer to the
information in an XML document.
Candidate Recommendation Plans and Exit Criteria
The purpose of this XML Information Set specification is to provide
definitions for use in other specifications; definitions of what
structure is represented by the syntax of an XML document was not
included in the original XML specification, but a number of
technologies layered on XML have needed such definitions, and have
* The Document Object Model is an API for manipulating the
structure represented by an XML document.
* XPath gives a syntax for selecting parts of the structure
represented by an XML document; this syntax is defined in
terms of a data model; this XPath data model is used in the
XSLT and XPointer specifications.
* The XML Canonicalization specficiation is also based on
the XPath data model.
* The XML Schema specification is defined in terms of the
information represented by an XML document, not in terms
of the character-sequence syntax.
* The XInclude specification is defined as merging document
* The XML Query algebra is based on a data model for XML.
Implementation of this XML Information Set specification consists
primarily of its use in such layered specifications.
Feedback from working groups developing such layered specifications is
expected to provide the bulk of evidence of implementation experience of
the XML Information Set.
Of course, feedback from software developers who find the XML
Information Set specification is welcome. Feedback from those developing
training materials regarding the structure of XML documents is also in order.
Status of this Document
This specification of the XML Information Set is a
Candidate Recommendation of the World Wide Web Consortium.
One of the main purposes of the CR period is to gain
feedback based on implementation experience. Because its
purpose is to provide definitions for use in other
specifications, implementation of this specification
consists primarily of its use in those specifications.
The XML Core Working Group invites comments on the
specification thru 15 Jun 2001, at which point we expect
to have sufficient evidence of implementation to advance
to Proposed Recommendation. Comments should be sent to
firstname.lastname@example.org; An archive is available
to the public at
For background on this work, please see the XML Activity
Statement. This specification is a product of the XML Core
See the XML Information Set Requirements for the specific
requirements that informed development of this specification.
