Hi Anne,

Thanks for all the great XACML work :-)

There's a minor error on line 1674 (page 44, PolicySet line [071]) of oasis-####-xacml-1.0.pdf: please remove the trailing slash.

I don't see anything in XACML relating to resource labels (in fact the word label doesn't appear at all in oasis-####-xacml-1.0.pdf!). Resource labels are part of the authorization support in the X.509 standard and are used in several RBAC implementations. Resource labels are useful in enabling resource characteristics (i) to be set on resources and (ii) to form part of access control decisions. I feel sure that you must be aware of this and can only conclude that a PolicySet is intended to act as a resource label (in addition to acting as a policy set!). Is this correct?

Warmest regards,
