Norm hopes to be there; Liam and David plan to be there,
so there is a chance we could have a meeting.

Paul won't be there, and we assume John wouldn't.

Henry, Loren, Mohamed, Jirka, what are the chances you
will be at the October TPAC in Sapporo, Japan?

> Question about normalization checking in XML 1.1
> ------------------------------------------------
> John Cowan forwarded an email for us to consider at
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2014Dec/0026
> which I've also forwarded to the xml-editor list at
> http://lists.w3.org/Archives/Public/xml-editor/2014OctDec/0000
> for official/archive purposes.
>
> Paul wrote some comments in email at
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2014Dec/0028
>
> Henry checked with Richard who agrees it's a bug, though how
> to fix it isn't obvious. Probably the only candidates for not
> being normalized are (internal and external) doctypes per email at
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2015Jan/0004
>
> ACTION to Norm and Henry: Review the email about normalization checking
> in XML 1.1 and suggest an appropriate corrigendum.

ACTION to Norm and Henry continued.

> Potential Erratum to Namespaces
> -------------------------------
> CMSMcQ raised a potential erratum against Namespaces at
> http://lists.w3.org/Archives/Public/xml-names-editor/2014Sep/0000
> with WG discussion started at
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2014Sep/0019
>
> He says that our latest wording in the definition of 'namespace name'
> (section 2.1) appears to say that an element with no namespace binding
> in scope is in no namespace as opposed to saying its namespace is
> unknown (thereby leaving the possibility that its namespace
> information may be determined by some other methods).
>
> Norm, Paul, and Henry posted some thoughts on this, and none
> of us feel that the current wording is necessarily bad enough
> to be worth any change. In particular, Norm doesn't agree with
> what Michael thinks should be the case. Henry points out that
> HTML5 does "make use of" defining namespaces without the
> namespace spec mechanism.
>
> Henry had some more (private) exchanges with Michael, and
> Henry will summarize the discussion for the WG.
>
> ACTION to Henry: Summarize and provide current status of
> the discussion of this namespace potential erratum.

ACTION to Henry continued.

> 3. Submitting XML Schema 1.1 to ISO
>
> See also
> https://www.w3.org/XML/Group/Core#xml-schema
>
> We have decided we will first publish XML Schema 1.1 2E (with
> approved errata). After that, we would send XML Schema 1.1 2E
> (only) to ISO.
>
> Loren has offered to do the editorial duties, and David
> talked to CMSMCQ about getting some more help in the details.
>
> It looks like there are 3 bugs for Structures, none for Datatypes,
> but after checking with Michael, he found
> https://www.w3.org/XML/Group/2004/06/xmlschema-1/structures.errata-2012.html
> which shows 8 errata items whereas bugzilla shows only 3.
>
> We discussed
> https://www.w3.org/XML/Group/2004/06/xmlschema-1/structures.errata-2012.html
>
> Henry figures we can just publish this document.
>
> Loren believes the latest document includes everything,
> so the next step is to push it through the tool chain.
>
> We will need a diff (or list of changes).
> Loren says the diff is already available.
>
> We needed to consider whether any of the changes are normative
> and/or require a change to the test suite.  After some discussion,
> we decided we should just create a PER.
>
> ACTION to Loren:  Create the PER, i.e., XML Schema 1.1 Second Edition,
> and post (e.g., at http://www.w3.org/XML/Group/2014/12/xschema11.html)
> for the WG to review (talk to Paul if you need help so posting).

ACTION to Loren continued.

> 4.  XML Test Suite.

> See also http://www.w3.org/XML/Group/Core#xml-test-suite

> 5. LEIRIs--see http://www.w3.org/XML/Group/Core#leiri
>
> We have planned to issue the following spec editions referencing
> LEIRIs (and any outstanding errata):
>
> * XML 1.0 6th Edition (John to be editor)
> * XML 1.1 3rd Edition (John to be editor)
> * XInclude 3rd Edition (Paul to be editor)

> 6.  XInclude 1.1--see http://www.w3.org/XML/Group/Core#xinclude

> On 2012 February 14, we published

> On 15 January 2013, we published our (first) Last Call of

> On 2013 October 8, we published the XInclude 1.1 CR at

>
> Norm reports that Michael Kay's code just accesses Xerces code,

>
> ACTION to Norm:  Continue to work toward getting XInclude 1.1
> implementations and document them in our implementation report.

ACTION to Norm continued.

Norm filed an issue on the Xerces issue tracker to support XInclude 1.1;
he has heard there is a possibility that the Xerces folks would do it.
  

> Note also the desire for another test case for the XInclude test suite per
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2014Apr/0000
> Norm may see if he knows anyone still working on Xerces.
>
> Norm is planning to write a SAX filter to implement XInclude 1.1.
> He believes this will lead to a way for using XInclude 1.1 with
> Saxon's XSLT processor and most any other Java based tool.
>
> Jirka has implemented a subset of an XInclude processor
> in XSLT; it deals mainly with the new copy-attributes feature.
>
> We have published (another) Last Call 2014 December 16 at
> http://www.w3.org/TR/2014/WD-xinclude-11-20141216/
>
> The Last Call period ended January 17.  There were no comments.
>
> On the Feb 4 telcon, the WG had CONSENSUS to take XInclude 1.1 to CR.
>
> Paul drafted a Transition Request (including SOTD wording) at
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2015Feb/0010
> Liam said Paul should send it to Ralph and PLH (not Philipp Hoschka).
> Liam said we might not need a telcon.
>
> Norm announces that he has one conforming implementation,
> the one in XML Calabash, and he is working on another.
>
> Norm is trying to get Elliotte Rusty Harold's Sax filter
> that does XInclude, and he would like to get that updated
> to support XInclude 1.1.
>
> ACTION to Norm:  Update the implementation report and test suite.

ACTION to Norm continued.

> ACTION to Norm:  Create the pub-ready CR taking into account the
> wording/URLs in Paul's draft Transition Request (but make the
> proposed pubdate [and corresponding URLs] some reasonable future
> date).

ACTION to Norm continued.

>
> 7. MicroXML
>
> MicroXML is not in our new charter, but we can discuss it.
> We will leave this as an ongoing item in our standing agenda.
