shouldn't the draft use the full name, rather than the ambiguous 'XML
Schema') + some extra validation facilities makes life easier for
implementers and authors alike, in that they know what they can expect - you
get a stable base and simpler portability.

type applications should make it an ideal partner for forms based
applications.
