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: Switch expressions are to have same error semantics as 
typeswitch.  (See Bug 290320).


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-626-01: Mike to fix F&O example to use correct XPath.  J4.7.2 
Bug 29310 - [FO31] Invalid and ambiguous XPath expression in normative

that branch is selected.  ALSO add a note to clarify that in "if 
(condition) then 'z' else error()" z cannot be returned without 
evaluating the condition.  Q2.3.2 Bug 29320 - [XQ31] Switch expressions

J3. Maintenance Issues

J3.0 The XML Query WG and XSLT WG do not intend to maintains specs

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

         consultation.

XSLT WG documents
