[xacml] conformance tests updated

I finally found a validating parser that I can use.  As a result,
I have fixed a number of syntax errors in the conformance tests,
and have added some additional tests.

I have sent the updated tests to Michiharu to copy to the TC web
site.  If you plan to run conformance tests soon, please wait for
the updated tests to be available.
