           Summary: super/sub -set constraints missing for born-binary
                    pattern, enumeration respectively
           Product: XML Schema
           Version: 1.0/1.1 both
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Datatypes: XSD Part 2
        AssignedTo: cmsmcq@w3.org
        ReportedBy: ht@inf.ed.ac.uk

Nothing in the REC stops me from having an enumeration facet whose value is a
superset of its base type definition's, or a pattern facet whose value a subset
of its base type definition's.  This violates subsumption.  The XML
representations of such facets are disallowed, but nothing stops born-binary ones.
