all comments welcomed and solicited.

Before I can send in the request, we still need:

1.  replies from commentors in DoC (XML Sec WG)

4.  WG approval to request PR (at the telcon this week)

The XML Core WG requests transition of 
  Canonical XML 1.1
available at
http://www.w3.org/XML/Group/2007/12/PR-xml-c14n11-20071211.html
to a Proposed Recommendation.  

The URL cited above is for the most recent Member-only 
version of the specification as of @@ January 2008 but         @@@
dated 29 January 2008 in anticipation of publication then.  

That file is set up to be published by moving it to
http://www.w3.org/TR/2008/PR-xml-c14n11-20080129/Overview.html 

The C14N 1.1 specification had been published on 21 June 2007 
at http://www.w3.org/TR/2007/CR-xml-c14n11-20070621/
as a Candidate Recommendation. 

The CR comments have been considered and resolved, and 
a notification of the fact sent to every commenter.  There
were no outstanding objections raised during the CR period.

The document being sent to PR contains changes made to
accommodate CR feedback.  The changes made between CR and 
PR were editorial corrections or clarifications suggested 
by the implementation experience.  Review versions with 
differences highlighted are available as described in the SOTD.

There is a Disposition of Comments outlining the status at
http://www.w3.org/XML/2007/12/CR-c14n11-doc.html

An Implementation Report is available at
http://www.w3.org/2007/xmlsec/interop/xmldsig/c14n11/report.html
(thanks to the XML Security Specifications Maintenance Working Group).

There have been no changes in patent disclosures since CR:
http://www.w3.org/2004/01/pp-impl/18796/status#disclosures 
(there are no disclosures).

The WG's decision to request transition to Proposed 
Recommendation was taken during a teleconference on 
19 December 2007 whose minutes may be found at                @@@

IMPLEMENTATION REPORT

There is an Implementation Report at
http://www.w3.org/2007/xmlsec/interop/xmldsig/c14n11/report.html

PROPOSED PR 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

A list of current W3C publications and the latest revision of this 
technical report can be found in the W3C technical reports index

Publication as a Proposed 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.

Proposed Recommendation comments on this document are invited. 
Comments on this document are due by 7 March 2008, 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. 

The implementation report details CR implementation feedback from 
several implementations. It should be noted that this IR reflects 
results implemented against the CR as clarified based on issues 
raised during the CR period and subsequently reflected in the wording 
of this Proposed Recommendation. See the Disposition of Comments
for the CR feedback and resolution.

A review version with changes from the 1.0 version highlighted is 
available. A review version with changes since the Candidate 
Recommendation version highlighted is available.

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.



Paul Grosso and Norman Walsh, chairs of the XML Core WG.
