SUMMARY OF DECISIONS
====================
Note to secretary: Please insert a summary of all decisions made during
this teleconference at this location in the minutes.

Decisions MUST be clear as to their complete intent.  The subject of the
decision should *not* require dereferencing; it is most helpful if
agenda numbers and bug numbers are accompanied by their titles.  If a
decision is recorded about the resolution of a bug, the decision must
state exactly what the resolution is (e.g., "Accept the solution in
comment #5", or "Replace the production for XXX with this: <new
production>", or the like.  It should be possible to read a decision
months later and be certain what it meant and whether or not it was
properly applied.

## Decision: Resolve Bug 29975 as follows:

1. Make sure that XDM correctly assigns xml:id in all cases, including lax
2. Add to the rules for XQ/XT validation: "If the instance being validated contains an xml:id attribute, both lax and strict validation cause this attribute to be subjected to [xml:id] processing: that is, the attribute is checked for uniqueness, and is typed as xs:ID, and the containing element is therefore eligible as a target for the id() function."

## Decision: Close Bug 29976 with no change to the schema.  Michael will add a clarifying note.

## Decision: We will modify our stylesheets to publish specs in HTML5, per current W3C rules.

## Decision: Adopt proposed resolution for Bug 29959.



NEW ACTION ITEMS
================
Note to secretary: Please insert all new action items assigned during
this teleconference at this location in the minutes.

Action items MUST make sense even when they are viewed standalone (that
is, not read in the context of the agenda item where they were
assigned).  This explicitly requires that all referents (e.g., "this",
"that") be made clear.  Action items such as "Ralph to resolve this
problem" are DISALLOWED.  It takes a scribe only a few additional
minutes to ensure that action items are clear, while it takes the entire
WG considerable effort to constantly research the meaning of unclear
action items.  The subject of the action item should *not* require
dereferencing; it is most helpful if agenda numbers and bug numbers are
accompanied by their titles.

## Action A-660-01:  Jonathan to review Josh's resolution to bug 29858.

## Action A-660-02: Jonathan to add resolution of Bug 29975 to XQuery / XPath.

## Action A-660-03: Mike to add resolution of Bug 29975 to XSLT.

## Action A-660-04: Mike to add a note to F&O to explain that the outermost element of fn:analyze string allows mixed content.  See Bug 29976.

### Action A-660-05: Mike to modify stylesheets to produce HTML5 for the XSLT spec and notify other editors.

### Action A-660-06: Jonathan, Andy, Josh to ensure that their documents build with the new stylesheets.

## Action A-660-07: Jonathan to kick off an email discussion on Bug 29959, trying to create a proposal for fn:put().

## Action A-660-08:: mdyck to incorporate resolution of Bug 29959 in the grammar.

## Action: A-660-09:

This agenda item is reserved for reporting errors and other problems
reported against the 3.0 (later, 3.1) suite of specifications.

completion delays of XSLT 3.0 if XPath 3.0 is made obsoleted by 3.1

J5.1.1 Current status

* In Candidate Recommendation; awaiting implementation reports

* Potential coordination of dates with XSLT 3.0


J5.1.2 Dependencies inhibiting progression

* Closing any significant gaps in the test suite
  - Visualisation of this needs attention

* Detailed review of specifications by WG

Participant assigned to each document for detailed review
  - XDM 3.1           - Liam/Andy
  - XPath 3.1         - Mike Kay  - completed

no great enthusiasm for doing the work.  We cannot progress without plans
for a test suite and potential implementers.  The WG needs to decide what
to do with this spec.

Status: Ready to discuss

J6. Any other business

J6.1 Consideration of future work

J6.1.1 QT 3.2

The WGs decided that we will finish the 3.1 documents presently under way,
but undertake no new work. Maintenance work should be planned upon for a
period of time after finishing the specifications.


J6.1.2 FT 3.1

Currently inadequate interest and resources


J6.1.3 Update 3.1

Currently inadequate interest and resources



J7. Adjourn




=======================
XML Query Working Group
=======================

Q1. The XML Query WG does not intend to maintains specs earlier than the
3.0 suite of documents; when the 3.1 suite reaches Recommendation,
maintenance of the 3.0 documents will be terminated.

Q1.0 This agenda item is reserved for reporting errors and other
problems reported against the 3.0 (later, 3.1) XML Query WG suite of
specifications.


Q1.1 Bugzilla Bugs filed against the 3.0 suite of XML Query WG documents

(none)



Q2. Active Specification Development

Q2.1 XQuery Update Facility 3.0 (John)

Q2.1.0 Internal working draft
http://www.w3.org/XML/Group/qtspecs/specifications/xquery-update-30/html/Overview.html
http://www.w3.org/XML/Group/qtspecs/specifications/xquery-update-30/html/Overview-diff.html
http://www.w3.org/XML/Group/qtspecs/specifications/xquery-update-30/src/changes.txt

* The WG needs to obtain implementation experience with this document.


Q2.2 XQuery Update Facility 3.0 Requirements and Use Cases (Andy)
See
http://www.w3.org/XML/Group/qtspecs/requirements/xquery-update-30/html/Overview.html

* The WGs need to be certain that this document is completed
(red/yellow/green bullets on requirements, all the use cases intended to
be published) and a decision made to advance it to WG Note.


Q2.3 XQuery 3.1 (Jonathan)

Q2.3.0 Internal working draft
http://www.w3.org/XML/Group/qtspecs/specifications/xquery-31/html/xquery-31.html
http://www.w3.org/XML/Group/qtspecs/specifications/xquery-31/html/xquery-31-diff.html
http://www.w3.org/XML/Group/qtspecs/specifications/xquery-31/src/changes.txt


Q2.3.1 Bug 29959 - [xq31] fn:put()
https://www.w3.org/Bugs/Public/show_bug.cgi?id=29959

Status: Ready to discuss

## Action: A-660-07: Jonathan to kick off an email discussion on Bug 29959, trying to create a proposal for fn:put().

Some ideas:

1. Refer normatively to fn:put() in XQuery update 1.0, MUST support that, MAY support any later version.

2. new-docs(nodes) - multiple?

new-doc(node, uri) creates a document whose content is a copy of node, with document-url URI; by API convention a document in the result of the query that has a document URI is written to that location

Q2.3.1 Bug 29959 - CurlyArrayConstructor does not use EnclosedExpr
https://www.w3.org/Bugs/Public/show_bug.cgi?id=29989

## Decision: Adopt proposed resolution for Bug 29959.
