XML Query/XSL WG Joint Teleconference #639 Minutes 2016-04-12

> 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.

* Bug 29534
Decided: we will adopt the proposal in this comment:
https://www.w3.org/Bugs/Public/show_bug.cgi?id=29534#c1
The function was previously underspecified, these tests are new, so there is no real compatibility issue with XQuery 3.0.

* Bug 29408
Decided: Add text along these lines to the F&O specification:

   "implementation_defined" for results of calculations with
   xs:decimal or derived types *SHOULD* be at least the minimal
   requirement for the number of digits to be supported for xs:decimal

Tests will reflect the above semantics.

> 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-639-01: Mike to resolve Bug 29534 and modify the tests as
stated in https://www.w3.org/Bugs/Public/show_bug.cgi?id=29534#c1

* Action A-639-02: Mike to evaluate his proposal in
https://www.w3.org/Bugs/Public/show_bug.cgi?id=29555#c1 in light of
Tim's response wrt fractional seconds in #c2.

* Action A-639-03: Jonathan to send email saying he believes that
Bug29277 is now fixed, including functions with out an explicit
content expression, and encourage people to read the text with an eye
to adopting it next week.

* Action A-639-04: O'Neil to remove tests that are not XQuery 3.1
features from the XQuery 3.1 test suite

* Action A-639-05: O'Neil to report on tests that do not yet have
sufficient implementations
