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: Accept the proposal in Bugzilla for bug 29722 (fn:sort and array:sort, collation argument), with amendments as recorded in bugzilla.
DECISION: Bug 29723 (options parameter to map:merge to control duplicates). Proposal in comment 2 accepted, as modified by comment 6, but implementation-dependent rather than implementation-defined.
DECISION: Bug 29749 (rounding of fractional seconds): adopt the proposal (A) in comment (1).
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-651-01: MHK to implement the proposal for bug 29722 (fn:sort, array:sort with collations) as amended.
ACTION A-651-02: MHK to implement resolution of bug 29723 (options parameter to map:merge to control duplicates). Proposal in comment 2 accepted, as modified by comment 6, but implementation-dependent rather than implementation-defined.
ACTION A-651-03: MHK to implement the decision on bug 29749 (rounding of fractional seconds): adopt the proposal (A) in comment (1).
ACTION A-651-04 (Bug 29743: recursive maps) MHK to write a proposal for an fn:find() function. (But note, we are in no way committed to adopting this).

(none)
J2. Documents For Review
(none)

J3.0 The XML Query WG and XSLT WG do 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.
This agenda item is reserved for reporting errors and other problems
reported against the 3.0 (later, 3.1) suite of specifications.
J3.0.1 Concerns raised by the XSLT working group in regards to potential
completion delays of XSLT 3.0 if XPath 3.0 is made obsoleted by 3.1

consultation.

J4. Active Specification Development
** Note: Full Text 3.1 has been removed from the WG agenda.

Status: Ready to discuss - see proposal in comment 2
§§ DECISION: Bug 29723 (options parameter to map:merge to control duplicates). Proposal in comment 2 accepted, as modified by comment 6, but implementation-dependent rather than implementation-defined.
§§ ACTION A-651-02: MHK to implement resolution of bug 29723 (options parameter to map:merge to control duplicates). Proposal in comment 2 accepted, as modified by comment 6, but implementation-dependent rather than implementation-defined.

J4.4.1 Bug 29743 - XPath 3.1 maps recursive descent
https://www.w3.org/Bugs/Public/show_bug.cgi?id=29743
Status: Ready to discuss
§§ Jonathan suggests there is a requirement and it can be met using a map:flatten function. (Jonathan outlined how this might work but I didn't capture all the detail). It's clear it would be a fairly complex function.
§§ Abel says we spent some time on this in XSL WG and had trouble defining it, perhaps because our data model is considerably richer than JSON.
§§ MHK suggestion: fn:find($x, "string"): returns an array containing all the values associated with the key "string" at any depth, recursing through sequences and arrays at any level.
§§ Josh: 3 possibilities: do nothing, do something expedient, do something ideal.
§§ Andy defining a new operator at this stage would set us back months. A new function feels more containable.
§§ ACTION A-651-04 (Bug 29743: recursive maps) MHK to write a proposal for an fn:find() function. (But note, we are in no way committed to adopting this).
J4.5 Grammar Test Applets (Michael Dyck)
(none)
J4.6 QT3 test suite (O'Neil)
J4.6.1 Status report on test suite, harness, tools
J4.6.2 Status of 3.1 tests results

J5. Progression of Work
J5.1 XSLT 3.0, XQuery 3.1, XQueryX 3.1, XPath 3.1, XDM 3.1, F&O 3.1,
Serialization 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
* Completion of test suite minimum-required-to-declare-victory
* Sufficient implementation experience and reports thereof
* Formal response to all comments, responses accepted by commenters
* PR Transition Request and authorization, PR pub request
* REC Transition Request and authorization, REC pub request
J5.2 Update 3.0
J5.2.1 Current Status
* In Last Call Working Draft
At XML Prague, Liam talked to a few people about XQuery Update but found 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
J5.2.2 Require owner of XQUF 3.0 Test Suite
J5.2.3 Dependencies inhibiting progression
* CR Transition Request and authorization, CR pub request
* Completion of test suite minimum-required-to-declare-victory
* Sufficient implementation experience and reports thereof

* PR Transition Request and authorization, PR pub request
* REC Transition Request and authorization, REC pub request
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
