ACTION to Richard continued, should be done by next telcon.

Lew points out the namespace axis is now optional 
so namespace handling is quite different.

Both Lew and Richard thought this could be problematic
for users, but Richard wasn't sure this should be an
XML Core WG comment.

If individuals think this change is a problem, they
should make an individual comment about this.

Henry reports (after checking) that it will be published tomorrow.

Done, PE 139.

> 5. Namespaces in XML.

> Richard suggested we take NS 1.1 and revert the two

> 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

ACTION to Norm continued.

> ACTION to DV:  Run your implementation on the

ACTION to DV continued.

Norm has patched Amaya to recognize xml:id wrt CSS.

> Paul raised this issue at the XML CG.  In fact, Dan raised
> the issue on www-tag:

(selectors of #foo matching xml:id="foo").

ACTION to Paul:  Continued.

Then there's the thread started on public-xml-id arguing 
again for xmlid instead of xml:id. See
http://lists.w3.org/Archives/Public/public-xml-id/2005Apr/0013
and followup.

>From a purely technical aspect, either xmlid or xml:id
would work.  But namespaces was developed for this purpose,
and we think we should use it, and anything else would
likely surprise users for no substantial benefit.

> 
> 8.  Associating stylesheets--awaiting TAG action.
> 
> Henry noticed that the HTML CG has run into the same issue.
> There is an interaction between media types and secondary
> resource, and there appears to be no consensus on the HTML CG
> as to what should be the case.
> 
> Henry asked the HTML CG if they felt this issue should be
> taken to the TAG, but being as he just asked them, there 
> hasn't yet been a response.
> 
> ACTION to Henry:  Continue to see if this issue should
> be brought to the TAG.

Henry isn't getting a single voice out of the HTML CG.
He will continue to work on this.

> 
> 9.  absolutivity of [base URI]
>     Norm has asked a question about the absolutivity of [base URI]:
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2005Feb/0031
> 
> We discussed this at our f2f:
> http://www.w3.org/XML/2005/02/xml-f2f-20050303-minutes.htm#base-uri
> 
> We have CONSENSUS that base URIs are always absolute. 
> 
> Then we had a further issue about base URIs in the infoset.
> 
> Richard sent email to www-tag on this:
> http://lists.w3.org/Archives/Public/www-tag/2005Apr/0077

ACTION to Richard:  Review the responses.

> 
> 10.  XML Validity and DTD dependence.
>   Rich Saltz started the discussion at
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2005Apr/0026
> and there have been several sub-threads.  The discussion continues.

We aren't sure the WG and Rich are really understanding
each other.

ACTION to Paul:  See if Rich can attend a WG telcon.

> 
> 11.  XInclude, schema validity-assessment, xml:base and xml:lang
> 
> Henry kicked this off at:
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2005Apr/0039
> We didn't discuss this topic much ourselves, but Norm and Henry 
> both lean toward making it an issue for the XML Schema WG, so we 
> are waiting to hear from them.

We will take this near the beginning of the call next week
so that we have more time to discuss it.  People should read
the above URL before the telcon.
