[xacml] Fwd: AttributeDesignator examples

Attached are some examples of using [Subject]AttributeDesignator and Target
with the new schema syntax.  Simon and I came up with these after
the F2F today, so we were both pretty wiped out and they may not cover
the really interesting cases.  Please send comments if more cases
needed.
 P.S. syntax is not precise, but is conceptually same as schema 16d.
 16d does not yet include the multiple <SubjectMatch> elements that
 are ANDed together.  Multiple <Subject> elements are ORed together.
