   We had a good discussion of this last week and there has been plenty of
   activity since. This item is to check with the group to see if there
   issues that would benefit from immediate discussion or if the proposals
   are still proceeding apace.

  2.3. XPath 4.0 functions

   Based on offline conversations with MK, the order of functions in this
   list has been adjusted with a goal of giving priority to things that (a)
   should involve less discussion and (b) should involve less editorial work.

    2.3.1. fn:replicate

     * See
       https://qt4cg.org/specifications/xpath-functions-40/Overview.html#func-replicate

    2.3.2. The family of functions proposed as fn:range-from/fn:range-to and
    others

     * fn:range-from,
       https://qt4cg.org/specifications/xpath-functions-40/Overview.html#func-range-from
     * fn:range-to,
       https://qt4cg.org/specifications/xpath-functions-40/Overview.html#func-range-to
     * fn:items-before, fn:items-after, fn:items-from, and fn:items-until
          * Unspecified, see
            https://qt4cg.org/specifications/xpath-functions-40/Overview.html#new-functions
     * See also #149: functions for splitting a sequence (or array) based on
       predicate matching
     * Also related: fn:slice,
       https://qt4cg.org/specifications/xpath-functions-40/Overview.html#func-slice

   What approach should we persue in tackling this family of functions?
