> 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,
> but that make take help from Henry or Michael. Loren
> will try to contact Michael again.
>
> We will need a diff (or list of changes) and a test suite.
> Loren says the diff is already available.
>
> We need to see if any of the changes are normative.
> It appears that none of the changes require a chance
> in the test suite.
>
> ACTION to Loren and David:  Check if any changes are normative
> and/or would require a change to the test suite (and that aren't
> already supported by implementations).
>

David has produced a table outlining his thoughts on the
normativity of the various changes.  He will be sending
it to the WG list shortly.

The WG should review that table so that we can discuss
this at our next telcon.


> ACTION to Loren:  Check that he can run the build.
>

ACTION to Loren continued.


Editing the XML Schema namespace document
-----------------------------------------
ACTION to Norm: Edit the XML Schema namespace document
at http://www.w3.org/2001/XMLSchema.html
to add a reference to XML Schema 1.1 and to xs:numeric.


> 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.

> 3.  XML Test Suite.
>
> See also http://www.w3.org/XML/Group/Core#xml-test-suite
>
>
> 4. 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)
>
> but all this is on hold awaiting resolution of IRIbis.
>
>
> 5.  XInclude 1.1--see http://www.w3.org/XML/Group/Core#xinclude
>
> On 2012 February 14, we published
> XInclude 1.1 Requirement and Use Cases
> http://www.w3.org/TR/xinclude-11-requirements/
>
> On 9 October 2012, we published our FPWD of XInclude 1.1 at
> http://www.w3.org/XML/2012/10/WD-xinclude-11-20121009/
>
> On 15 January 2013, we published our (first) Last Call of
> XInclude 1.1 at
> http://www.w3.org/TR/2013/WD-xinclude-11-20130115/
> and Paul sent the transition announcement at
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2013Jan/0012
> (also cc-ing the chairs mailing list).
> On 2013 October 8, we published the XInclude 1.1 CR at
> http://www.w3.org/TR/2013/CR-xinclude-11-20131008/
>
> Norm reports that Michael Kay's code just accesses Xerces code,
> so Norm might have to work with Xerces.
>
> DV reports that he is busy and so cannot commit to a deadline
> for adding XInclude 1.1 support to libxml.
>
> ACTION to Norm:  Continue to work toward getting XInclude 1.1
> implementations and document them in our implementation report.
>
> 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.
>
>
> Norm raised an issue at
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2014Sep/0004
> pointing out a problem copying the xml:base attribute
> when the xi:xinclude element itself has an xml:base attribute.
> After WG discussion, we decided we need to be clearer in general
> about how xml:id, xml:lang, and xml:base are handled when they occur
> on the xi:include element including how they get their semantics.
>
> ACTION to Norm:  Write a proposal for how to address this problem.
>
ACTION to Norm continued.


> 6. 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.
