           Summary: RQ-141e: Make pattern value be a set of regexes, not one
           Product: XML Schema
           Version: 1.1
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSD Part 2: Datatypes

This item is a spinoff from the editors' work on RQ-141b.

In the course of fixing an alignment problem between Structures
and Datatypes as regards the enumeration facet, the editors
saw an opportunity for an analogous change to the pattern facet:
make its {value} be a set instead of a single regular expression,
and change the facet merger rules in Structures to perform the
correct set union operation on the facet created in the restriction
step and the pattern facet of the base type.

Since this change is not essential to reconciling Structures
and Datatypes, and since it involves a design choice which ought
to be made by the WG, it has been factored out from the larger
proposal for RQ-141b to make separate consideration easier.
