I'd add:

C)	Allow system entities to use standard XML tools and the PWG (and
potentially other) schemas to determine that a request is well formed
D)	Facilitate development around the PWG semantic model by creating
schema structures that expose both objects and values through commonly used
development tools

As for B), I'd say the semantic model certainly needs to enable capabilities
to be ascertained, but I'm not honestly sure whether it's in scope for the
SM project to "completely" solve this.  It may be sufficient here just to
declare the objects & values in such a way that they can be readily used by
capabilities schemes, and that the "full" capabilities problem will be
solved in forums like PSI & UPDF.
