----------

We have been asked to review
"XML Schema 1.1 Part 2:  Datatypes"
http://www.w3.org/TR/2006/WD-xmlschema11-2-20060116/

John Cowan volunteered and sent his comments to the list at
http://lists.w3.org/Archives/Public/public-xml-core-wg/2006Feb/0029


2b.  IRI wording in xml:base et al.

Chris Lilley asks about xml:base and IRI:
http://lists.w3.org/Archives/Public/public-xml-core-wg/2005Oct/0004

Norm thinks we should change the bib ref from 2986
to 3986.  Section 3.1 should say any xml:base should
first have spaces escaped to %20 and then have the
IRI changed to a URI per 3987.

We should have uniform language for XLink 1.1, XLink 1.0,
xml:base, xinclude, XML 1.0, and XML 1.1 (as errata for 
all but XLink 1.1).

There is some question as to whether we should bother to 
make an erratum for XLink 1.0, but we did not resolve this.

We basically want to put the text that is in XLink 1.1 into
the other specs.

We talked about pulling the necessary wording into a normative
appendix in XML 1.0 3rd Ed and XML 1.1 (as errata in both cases).
Then we could reference that appendix in xml:base, XInclude, etc.

We also said we could just make it section 4.2.3.  As long as it
is referenceable by other specs.

Francois sent updated suggestions at
http://lists.w3.org/Archives/Public/public-xml-core-wg/2006Jan/0016
(ignore the "System identifiers (and other XML strings..." 
sentence at the beginning.)

This will go into XLink 1.1 as a separate section.  
Then we can do it as an erratum for XML 1.0 and 1.1.
Then we would produce XML 1.0 4th Ed and 1.1 2nd Ed.
XInclude and xml:base (and probably NS 1.1) we do 
errata pointing them to the new editions of XML or 
if we're in a bigger hurry, errata quoting the whole 
text.  (We don't want to point the lower specs to XLink.)  

Richard made some comments on this at
http://lists.w3.org/Archives/Public/public-xml-core-wg/2006Feb/0027
and Norm replied at
http://lists.w3.org/Archives/Public/public-xml-core-wg/2006Feb/0028
ending with a question for Francois.

We do have a suggestion from Murata-san at
http://lists.w3.org/Archives/Public/xml-names-editor/2005Dec/0000
that we process such an erratum against NS 1.0.

We're not sure what we think about this yet.


3.  XLink update.

The LC WD of XLink 1.1 has been published:
http://www.w3.org/TR/2005/WD-xlink11-20050707/

We have comments at
http://lists.w3.org/Archives/Public/www-xml-linking-comments/2005JulSep/
and an issues document at
http://www.w3.org/XML/2005/xlink11/lc-status/status-report.html

Norm put a DoC at
http://www.w3.org/XML/2005/xlink11/lc-status/doc.html

Paul sent a draft CR request at
http://lists.w3.org/Archives/Public/public-xml-core-wg/2006Jan/0019

Norm has sent out the latest CR-ready draft at
http://www.w3.org/XML/Group/2004/xmlcore/xlink11/


xlink:href requirements 
-----------------------
http://lists.w3.org/Archives/Public/www-xml-linking-comments/2005JulSep/

Last message at
http://lists.w3.org/Archives/Public/www-xml-linking-comments/2006JanMar/
0063

Change "xml string" to "character string".

The meaning of our definition of href hasn't changed since
Last Call though the wording has changed.

ACTION to Norm:  Take another stab at answering this question.

error handling 
---------------
Last message is at
http://lists.w3.org/Archives/Public/www-xml-linking-comments/2006JanMar/
0002
and we don't understand this really.

We don't talk about reporting errors, we just say
some elements have xlink semantics and others don't.

Norm and Richard (mostly) discussed this.

ACTION to Norm:  Try to email back again to try to see
what it is he is getting at.


4. XML errata.  The published 1.0 errata document is [8], the
   published 1.1 errata document is [9], and the new (public)
   Potential Errata (PE) document is [7]. 

JohnC did a scan for MUST/SHOULD and reported at
http://lists.w3.org/Archives/Public/public-xml-core-wg/2005Oct/0015
John thought most of the mays were not official mays.

This is now PE 148.

ACTION to Henry [due Feb 22]:  Review the MAYs again and 
create a marked up version with changes.


5. Namespaces in XML.

Richard suggested we take NS 1.1 and revert the two 
substantive changes (IRI and undeclared namespaces) 
to create NS 1.0 2nd Ed. The WG has consensus to do 
that, and we got approval from the team to do so.

Ongoing ACTION to Richard:  Produce a draft for NS1.0 2nd Ed.

We note that the IRI spec is now finished-RFC 3987-so 
we have to issue an erratum for NS 1.1 for this.  We
discussed some details of this under the XLink discussion:
http://www.w3.org/XML/2005/02/xml-f2f-20050303-minutes.htm#xlink
Briefly, 3987 does have some wording (the "MAY" paragraph) 
about what used to be called unwise characters.  For the 
NS 1.1 erratum, the MAY paragraph doesn't apply since 
namespace names cannot have the unwise characters.  (The 
MAY paragraph will be needed for XML 1.* system identifiers.)

ACTION to Richard:  Process an erratum to NS 1.1 to
refer to RFC 3987: http://www.ietf.org/rfc/rfc3987.txt

There is a namespace PE:
http://lists.w3.org/Archives/Public/xml-names-editor/2005Dec/0001

Richard's suggested resolutions are at
http://lists.w3.org/Archives/Public/xml-names-editor/2005Dec/0002

CONSENSUS with Richard's suggested resolutions.

These would be errata to both NS 1.0 and 1.1.

ACTION to Richard:  Update the NS PE doc and Errata documents.


6. Xinclude Rec was published 2004 December 30 at:
   http://www.w3.org/TR/2004/REC-xinclude-20041220/

Our XInclude potential errata document is at:
http://www.w3.org/XML/2005/01/proposed-xinclude-errata

Daniel has updated the Errata document at
http://www.w3.org/2004/12/xinclude-errata 


7. xml:id is a Recommendation, published 2005 Sept 9:
 http://www.w3.org/TR/2005/REC-xml-id-20050909/

Robin Berjon asked a question about transition
strategies that we should discuss--see
http://lists.w3.org/Archives/Public/public-xml-core-wg/2006Jan/0049


8.  Associating stylesheets--awaiting TAG action.

Henry reports that the HTML CG has been discussing this
for a while.  They are developing a draft statement of
the issue, and Chris Lilley will raise this at the XML CG.

Chris started the discussion on the XML CG list--see
http://lists.w3.org/Archives/Member/w3c-xml-cg/2005Jul/thread.html#15
The XML CG will continue to discuss it for a while.


9.  C14N is listed in our charter:

 Canonical XML version 1.1

 The work on xml:id uncovered some inconsistencies
 in Canonical XML version 1.0 (see xml:id CR,
 Appendix C, "Impacts on Other Standards"). The
 Working Group will produce a new version of
 Canonical XML to address those inconsistencies,
 as well as others that might be discovered at a
 later stage.

We have CONSENSUS that we have been chartered to do a 1.1
and that we should not try to do this as an erratum.

We are not sure how best to do this as a 1.1.  We should try
to elaborate the possible ways of handling this and ask the
C14N community how best to go about this.  For example, if
we create a new namespace for C14N 1.1, what do we say the 
old namespace means?  We'd like to avoid the flak we are
getting for XML 1.1.

We should probably use the existing mailing list
w3c-ietf-xmldsig@w3.org to gather opinions.

Glenn posted an email to w3c-ietf-xmldsig@w3.org explaining
we are doing a 1.1 and asking for how we can minimize disruption:
http://lists.w3.org/Archives/Public/public-xml-core-wg/2005Dec/0001

Glenn summarized that discussion at:
http://lists.w3.org/Archives/Public/public-xml-core-wg/2006Jan/0012

The email includes a discussion on whether an erratum to C14N 1.0
or a C14N 1.1 would be less disruptive.  There was no consensus
among the discussants of this thread.

The XML Core WG has consensus to stick with a C14N 1.1 as chartered.

Henry points out we could produce a 1.1 and use the old identifier.
But Norm doesn't think we can do that.

Glenn created an editor's draft of C14N 1.1 which is up at
http://www.w3.org/XML/Group/2006/02/WD-xml-c14n11


10.  Henry added a "forking QNames" item:
http://lists.w3.org/Archives/Public/public-xml-core-wg/2005Nov/0000

We had some discussion last week.

Norm argues that we should object to the use of the
QName syntax for things that aren't QNames.  He also
objects to the invention of a new mechanism for declaring
things that look like namespaces when they aren't really.

Norm is still trying to understand whether there is an
issue yet, and he needs to wait until they publish a
document to be sure.

ACTION to Norm:  Raise this concern at the TAG level
at the appropriate time.


11.  Henry raises that RFC 3023 is out of date and the draft
replacement has expired.  Henry says there is a new draft
expected soon (Murata-san will send something to Chris to
publish soon).  

Chris is still hoping that he and Murata will be able
to publish a new ID for 3023bis soon.
