Message-ID: <CF83BAA719FD2C439D25CBB1C9D1D3020998C1D4@HQ-MAIL4.ptcnet.ptc.com>
To: <public-xml-core-wg@w3.org>

We have an XML Core WG phone call scheduled for Wednesday, 
December 5, from
          08:00-09:00 Pacific time aka
          11:00-12:00 Eastern time aka
          15:00-16:00 UTC
          16:00-17:00 in Ireland and the UK
          17:00-18:00 in middle (most of) Europe
on the Zakim W3C Bridge, +1 617 761 6200, passcode 9652#.
We also use IRC channel #xmlcore on irc.w3.org:6665 .

See the XML Core group page [1] for pointers to current documents
and other information.  If you have additions to the agenda, please
email them to the WG list before the start of the telcon.

Please also review our group page's task list [2] for accuracy and
completeness and be prepared to amend if necessary and accept it
at the beginning of the call.

1. Accepting the minutes from the last telcon [3] and
   the current task status [2] (have any questions, comments,
   or corrections ready by the beginning of the call).

Regrets from Norm and maybe DV for Dec 5.

2. Miscellaneous administrivia and document reviews.

We have a request from the Web Application Formats WG to review 
the Access Control for Cross-site Requests document.  The draft 
introduces a policy for performing cross-site requests (using GET 
and non-GET methods) which can be used by XMLHttpRequest, XSLT, 
<event-source>, XBL, etc.:


Reviewing the <?access-control?> processing instruction might be 
of particular interest to XML Core.

Any volunteers to review this?


MathML WG points out an upcoming WD of 

"XML Entity definitions for Characters"

and asks if anyone in the XML Core WG would be interested in
reviewing this.

The draft is being developed in public, 


and in particular an "editor's copy" available here:



OASIS has announced another XRI document for public review:

Extensible Resource Identifier (XRI) Resolution Version 2.0

The public review starts today, 3 December 2007, and ends 
1 February 2008.

More non-normative information about the specification and 
the technical committee may be found at the public home page 
of the TC at 

The specification document and related files are available here:

3.  C14N 

The C14N 1.1 Candidate Recommendation is published at

Known Issues with Canonical XML 1.0 (C14N/1.0) WG Note 
has been published at

Using XML Digital Signatures in the 2006 XML Environment 
WG Note has been published at

C14N 1.1 Interoperability testing was performed on 27 September.  
A report of the outcome is at:

We had productive discussions during our f2f--see:

We are planning to drop Appendix A and augment the prose
in 2.4. 

Frederick sent an updated redline version at:
In particular, see
for the PDF attachments.

ACTION to Glenn: Produce a new editor's draft reflecting 
the changes suggested in Frederick's updated redline. 

We noticed a problem in the merging process where 'Base' 
argument to join-uris ends with "..". 

ACTION to Thomas and Frederick: Get implementors to run 
this new test case and report the results.

ACTION to Henry:  Come up with an argument for going to PR
with what will be the next draft of C14N 1.1.

4.  xml:base, [baseURI], and IRIs -> HRRIs -> LEIRIs

The (Second Edition) XML Base PER has been published at

ACTION to Richard:  Produce another PER-ready draft
of XML Base referencing LEIRIs, to wit:

 Replace the first sentence of 3.1 with:

  The value of an xml:base attribute is a LEIRI [ref].

 Delete the second sentence; leave the third.

We need to remember to correct the IP part of the Status section per

4.5.  HRRIs -> LEIRIs

The latest HRRI draft was published as an ID on May 14 at

The most recent editor's draft is at

Martin's latest IRI draft (defining LEIRIs in section 7) is at 

We've exchanged some email with Martin about some details,  
but in general it looks like we'll be happy with the definition 
of LEIRIs in the new IRI RFC.  

Scheduling for the revised IRI RFC is still unclear.  Paul sent
email to Martin, but we have as yet no response.

5.  XLink update.

The XLink CR was published at

The latest almost PR-ready XLink draft is at

Norm posted a DoC at

Paul wrote a SECOND draft PR request at

ACTION to Norm:  Complete resolution of DoC.

ACTION to WG (need volunteer):  Update the Implementation Report.

ACTION to Norm: Produce a PR-ready draft of XLink 1.1 with 
a reference to the IRI RFC for LEIRIs such as:

 Section 5.4: 

 replace para starting:

  The value of the href attribute is an XML resource identifer...


  The value of the href attribute is a LEIRI [ref].

 and then delete subsection 5.4.1 but move the para about 
 relative references up into 5.4.

ACTION to Norm:  Suggest any other appropriate changes to XLink 1.1.

ACTION to Norm:  Produce diff/review version.

6. XML 1.0/1.1 4th/2nd Editions published 2006 August 16:

 Extensible Markup Language (XML) 1.0 (Fourth Edition)

 Extensible Markup Language (XML) 1.1 (Second Edition)

Henry/Richard discussed the test suite issues raised by Frans Englich:

These need to be resolved. 

Richard reports that the 2005 issue has been resolved in the latest

The one from 2006, character references with numbers with dozens 
of digits, may not be. 

ACTION: Richard to construct a test case for these issues.

Changes to XML 1.0 5th Edition and XML 1.1 3rd Edition:

Section 4.2.2 currently has a paragraph reading:

 System identifiers ... may contain characters that...must 
 be escaped before a URI can be used to retrieve the
 referenced resource. 

We decided to replace this (2nd para of 4.2.2) and the 
following 3 points by:

 System identifiers (and other XML strings meant to be used
 as URI references) are LEIRIs [ref].  Failure to match the
 applicable syntax productions of [LEIRI] is not an error.
 Note, however, system identifiers which do not conform to
 LEIRIs are not in practice likely to be useful. 

7. Namespaces in XML 1.0/1.1 2nd Editions published 2006 August 16:

 Namespaces in XML 1.0 (Second Edition)

 Namespaces in XML 1.1 (Second Edition)

Richard has recorded Anne's issue/proposed resolution at

8. XML 1.0 5th Edition

I had sent out email at
and we have gotten very little response--see

We had some discussion at our f2f--see

We appear to have unofficial agreement by most implementors
to consider making this change if it goes through the W3C

Paul talked to Ian Jacobs who suggested the best way to 
make this change is to issue an XML 1.0 5th Edition PER 
with a relatively long review period.

We appear to have consensus to change the name char productions
in XML 1.0 5th Ed.

We also have consensus to allow XML 1.0 processors to accept 
documents labelled version="1.x".

Other character changes remain to be decided (though the 
status quo is not to make any others).  In particular:

ACTION to Henry:  Check with Noah how IBM feels about #x85.

9.  XInclude 3rd Edition

XInclude 2nd Edition is at:

LEIRI-related changes for the 3rd Edition:

3.1, href attribute is a LEIRI

See also 4.1.1 (details TBD) which can't reference XML 1.1
since we don't define XML Resource Identifiers in XML 1.1.
Just replace that para with the "They are LEIRIs" para.

ACTION to Daniel: Produce a PER-ready draft of XInclude 3rd Ed
with appropriate references to the IRI RFC for LEIRIs.
