TPAC 26-30 October 2015 in Sapporo, Japan
See http://www.w3.org/2015/11/TPAC/

Norm hopes to be there; Liam and David plan to be there.

Paul, John, Henry, Loren, Jirka, Moz won't be there.

Paul indicated that we would plan to have a (small) meeting there,
though it will be up to Norm, Liam, and David to arrange.


XML Potential Errata
Comment that “or by the Byte Order Mark” is lacking in section 4.3.3:

Comment that an entity cannot “begin” with a BOM as suggested in section 

ACTION to John and Henry: Review and comment on the above two comments
on the discussion of BOMs in section 4.3.3 of the XML spec.


Comment about documents with an "empty DTD":

Henry suggests we could probably make the XML spec clearer here;
see also his comments at

Paul sent the WG response at
and there was more back from the commentor at

Henry referenced Paul's email at
especially Paul's suggestion in point 4, though Henry wasn't
sure he agreed with the suggestion.

ACTION to Henry:  Post some suggestion(s) to the list about
how to address: Comment about documents with an "empty DTD".


Question about normalization checking in XML 1.1
John Cowan forwarded an email for us to consider at
which I've also forwarded to the xml-editor list at
for official/archive purposes.

Paul wrote some comments in email at

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

ACTION to Norm and Henry: Review the email about normalization checking
in XML 1.1 and suggest an appropriate corrigendum.


Potential Erratum to Namespaces
CMSMcQ raised a potential erratum against Namespaces at
with WG discussion started at

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. Submitting XML Schema 1.1 to ISO

See also

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
which shows 8 errata items whereas bugzilla shows only 3.

We discussed

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).

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)

but all this is on hold awaiting resolution of IRIbis.

6.  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

On 9 October 2012, we published our FPWD of XInclude 1.1 at

On 15 January 2013, we published our (first) Last Call of
XInclude 1.1 at
and Paul sent the transition announcement at
(also cc-ing the chairs mailing list).

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

We have published (another) Last Call 2014 December 16 at

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
Liam said Paul should send it to Ralph and PLH (not Philipp Hoschka).
Liam said we might not need a telcon.

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.

Jirka has implemented a subset of an XInclude processor
in XSLT; it deals mainly with the new copy-attributes feature.

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

Norm announces that he has one conforming implementation,
the one in XML Calabash, and he is working on another.

ACTION to Norm:  Update the implementation report and test suite.

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

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.
