Schemas with choice groups replacing substitution groups

All,

	Attached are the schemas with the choice groups replacing the
substitution groups.

	I introduced extra elements for subject statement and query so that
extension schemas can key of them with an xsi:type duwinsky and give maximum
info to the other application.
