GWS Splinter: XSD Schema Evolution

[Brian Major]

Hi grid,

I'm happy to say that the discussion on XSD schema evolution resulted in
agreement on method.  In a nutshell:

1.  Clients are do to best-effort parsing (discourage schema validation)
2.  The XSD namespace is to be that of the major revision (x.0)
3.  For version discovery, the precise version shall be included in the
root element of the XSD and XML documents.
4.  Tests & validators are still to use XML validation

Paul Harrison has graciously offered to write up a note on our discussions
that will be sent out for review.

Brian
