RE: Restriction+choice+substitutionGroup

Thanks Henry,

SQC exhibits the same problem, and incidentally another problem with
finalDefault.

The more that I think about this problem, the stickier it gets.  The
comments here
are interesting and somwhat similar:
http://issues.apache.org/jira/browse/XERCESJ-922#action_35625

An in a similar vein, if the following statement is applied:
    Note: Although the ·validation· semantics of a choice group does
    not depend on the order of its particles, derived choice groups
    are required to match the order of their base in order to simplify
    checking that the derivation is OK.
How does the validating parser know the "order" of the elements in a
substitution group?

Regards,
Martin

Oops, my bad, sorry.
[MT] Might be mine actually, I'm using outlook :(

Schema Quality Checker, from IBM.  Doesn't do validation, but a very
thorough implementation of constraints on schemas/schema documents.
