2. Technical Agenda

  2.1. Approve proposed changes to fn:all and fn:some

   Mike completed his action. I’ve republished the PR so that it builds
   against the updated infrastructure.

  2.2. Approve changes in changes-agreed-2022-09-20 branch

   Mike created a branch which renames fn:uniform() and fn:unique() per his
   action QT4CG-003-04 and adds a few other editorial improvements.

  2.3. XPath 4.0 functions

     * See
       https://github.com/qt4cg/qtspecs/blob/master/editorial/functions-checklist.pdf

   The items that follow are taken from the PDF in roughly the order
   presented in the PDF. The agenda does not intend to assert that they must
   or should be discussed in precisely this order.

    2.3.1. Variadic functions

   Dimitre proposes that we should discuss variadic functions sooner rather
   than later:

     “WRT our dependency sorting, can we discuss with high priority and
     approve the XPath 4.0 variadic functions, so that immediately after that
     we could typically describe not N overloads of a proposed function, but
     just a single signature containing keyword arguments with defaults?”

    2.3.2. Move fn:deep-equal higher up the list?

   Dimitre observes “some of the functions to be discussed that are included
   in the current list/checklist, depend on using a compare() function /
   strategy. This makes all of them dependent on having first discussed and
   approved fn:deep-equal(options). Therefore, could we move
   fn:deep-equal(options) considerably higher in the list, so that it
   precedes all such functions that are dependent on a compare()
   function/strategy?”
