Implementations)

Dear Advisory Committee Representative,

I am pleased to announce that Canonical XML 1.1 is a W3C Candidate
Recommendation. The approval and publication is in response to the
following transition request:

The disposition of Last Call comments is available here:
    http://www.w3.org/XML/2007/05/c14n11-wd-doc.htm

There were no formal objections.

Patent disclosures relevant to this specification may be found on the
XML Core Working Group's patent disclosure page in conformance with
W3C policy:
      http://www.w3.org/2004/01/pp-impl/18796/status

The XML Core Working Group expects to receive more comments in the
form of implementation feedback and test cases. The Working Group
believes it will have satisfied its implementation criteria by 30
September 2007.

   Abstract
   --------

     Canonical XML 1.1 is a revision to Canonical XML 1.0 to address
     issues related to inheritance of attributes in the XML namespace
     when canonicalizing document subsets, including the requirement
     not to inherit xml:id, and to treat xml:base URI path processing
     properly.

     Any XML document is part of a set of XML documents that are
     logically equivalent within an application context, but which
     vary in physical representation based on syntactic changes
     permitted by XML 1.0 [XML] and Namespaces in XML [Names]. This
     specification describes a method for generating a physical
     representation, the canonical form, of an XML document that
     accounts for the permissible changes. Except for limitations
     regarding a few unusual cases, if two documents have the same
     canonical form, then the two documents are logically equivalent
     within the given application context. Note that two documents may
     have differing canonical forms yet still be equivalent in a given
     context based on application-specific equivalence rules for which
     no generalized XML specification could account.

     Canonical XML 1.1 is applicable to XML 1.0 and defined in terms
     of the XPath 1.0 data model. It is not defined for XML 1.1.


   Status of This Document
   -----------------------

     This section describes the status of this document at the time of
     its publication. Other documents may supersede this document. A
     list of current W3C publications and the latest revision of this
     technical report can be found in the W3C technical reports index
     at http://www.w3.org/TR/.

     Publication as a Candidate Recommendation does not imply
     endorsement by the W3C Membership. This is a draft document and
     may be updated, replaced or obsoleted by other documents at any
     time. It is inappropriate to cite this document as other than
     work in progress.

     Candidate Recommendation comments on this document are
     invited. Comments on this document are due by 30 September 2007,
     but earlier comments are expressly solicited. Comments should be
     sent to www-xml-canonicalization-comments@w3.org which is an
     automatically archived public email list. At this time, there is
     no implementation report. A review version with changes from the
     1.0 version highlighted is available:
       http://www.w3.org/TR/xml-c14n11/CR-xml-c14n11-20070509-diff.htm
     A review version with
     changes since the Last Call version highlighted is available:
       http://www.w3.org/TR/xml-c14n11/CR-xml-c14n11-20070509-diff2.htm

     The XML Core Working Group will advance the specification to
     Proposed Recommendation when the following exit criteria have
     been met:

	 * Test documents must have been developed with a range of
	   usages of attributes in the XML namespace, and correct and
	   compatible results shown for these tests by at least two
	   implementations.
         * A minimum of three months of the CR period must have elapsed.

     This document has been produced by the W3C XML Core Working Group
     as part of the W3C XML Activity. The authors of this document are
     the members of the XML Core Working Group and invited experts
     from the Digital Signature community.

     This document was produced by a group operating under the 5
     February 2004 W3C Patent Policy. W3C maintains a public list of
     any patent disclosures made in connection with the deliverables
     of the group; that page also includes instructions for disclosing
     a patent:
       http://www.w3.org/2004/01/pp-impl/18796/status
     An individual who has actual knowledge of a patent which the
     individual believes contains Essential Claim(s) must disclose the
     information in accordance with section 6 of the W3C Patent
     Policy.

     The English version of this specification is the only normative
     version.

This Call for Implementations follows section 7.4.3 of the W3C Process
