Publication Request: Candidate Recommendation for C14N 1.1

The XML Core WG requests publication of 
  Canonical XML 1.1
available at
http://www.w3.org/XML/Group/2007/05/CR-xml-c14n11-20070509.htm
as a Candidate Recommendation.  

The URL cited above is for the most recent Member-only 
version of the specification as of 2007 June 18 but 
dated 21 June 2007 in anticipation of that publication date.

That file is set up to be published by moving it to
http://www.w3.org/TR/2007/CR-xml-c14n11-20070621.html  

C14N 1.0 was published as a Recommendation on 15 March 2001 at
http://www.w3.org/TR/2001/REC-xml-c14n-20010315.html

The C14N 1.1 specification was published on 20 December 2006
at http://www.w3.org/TR/2006/WD-xml-c14n11-20061220/
as a Last Call Specification.  

A successful CR transition telcon was held on 2007 June 15:

A review version showing the differences between C14N 1.0 is at

The WG's decision to request publication as a Candidate 
Recommendation was taken during our telcon on 2007 May 23

We plan to run the CR period until the end of September 2007.


TITLE, ABSTRACT AND STATUS SECTIONS

Canonical XML 1.1
=================

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

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 differences between the 1.0 version 
highlighted is available.

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. 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.
