Done--there were no comments.

> ACTION to Richard:  Review the latest C14N 1.1 esp App A.

App A seemed to match what was a diff last time.

Konrad sent in some editorial comments at

ACTION to Glenn:  Make the editorial changes unless there are problems.

Plan to approve for LC publication at our next telcon in two weeks
and then publish the LC in mid-December in concert with the XML Base PER.

Jose suggested we republish the two WG Notes at the same time.
We forsee no changes to them except some references to new versions
of C14N 1.1 and XML Base.

Richard has updated the draft at
and created a draft of the errata page at

CONSENSUS to make this draft and errata page public.

ACTION to Richard and Henry:  Make the draft and updated errata
public and announce to chairs and xml-dev, etc. as appropriate.

We will plan to go to PER in mid-December.

We agreed that, according to the spec, such a character is not a BOM.

Henry suggested we should provide an explanation, but he's not sure
if it should go in the spec or just to the commentor.

We will pick this back up later when John is on the call.

We did have a comment on XInclude that we missed:


which was re-raised last month:


Henry suggests we accept in principle the commentors suggestion.

We have CONSENSUS to accept the commentors suggestion pretty
much verbatim:

 If the media type of the resource indicates,
 according to XML Media Types [RFC 3023], that the
 resource is XML--for example ...--then the encoding is determined
 as specified in [XML 1.0] or [XML 1.1] section 4.3.3,
 as appropriate.

where ... is the "for example" text currently in the spec.

ACTION to Daniel:  Implement the above change plus the IP change
to the status section plus any ???'s in the document and push it
to the Group XML space.

ACTION to Henry:  Send to DV the IP para and the pub date.

ACTION to Henry:  Take it from where Daniel put it and publish it.

> 9.  Associating stylesheets--awaiting TAG action.
> Henry reports that the HTML CG has been discussing this

> 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.
> 10.  Henry raises that RFC 3023 is out of date and the draft
> replacement has expired.  
> Chris has gotten the source and made the changes.
> There is a draft at
> http://www.w3.org/2006/02/son-of-3023/draft-murata-kohn-lilley-xml-02.txt
> that can be reviewed now with comments sent to the XML Core

> Paul sent some comments on 3023bis to the XML CG at
> http://lists.w3.org/Archives/Member/w3c-xml-cg/2006Apr/0026
> Henry says Chris is going to take the XML CG input outlined at
> http://lists.w3.org/Archives/Member/w3c-xml-cg/2006Apr/0019
> and produce another draft.
> We will now await a new draft from Chris.
