------- Comment #2 from cmsmcq@w3.org  2006-09-22 13:18 -------
I propose to resolve this by noting, first, that Sandy Gao is
correct to say in comment #2 that there is after all such a 
constraint for enumeration, in section 4.3.5.5 of Datatypes. 
To deal with pattern, I propose to add a section 4.3.4.5:

  4.3.5.5 Constraints on pattern Schema Components

  Schema Component Constraint: valid restriction of pattern

  It is an ·error· if there is any member of the {value} of the
  pattern facet on the {base type definition} which is not also a
  member of the {value}.

The Working Group has not yet taken action on this proposal.
