Permit-Overrides PolicyCombiningAlg

According to XACML 2.0 Appendix C.3 Permit-overrides, if the set of 
policy values being combined consists of Indeterminates and Denies, then 
the result is Deny.

This seems inconsistent with the intent of "Permit-overrides".  Had no 
error occurred, one of the Indeterminate policies might have been a 
Permit, and then the result would have been Permit.  Why are we treating 
an unknown that might have been a Permit as a Deny?

Regards,
Anne
