Subject: Re: [xacml-users] Base Policy (Ref: XACML 1.1 Specs)


Note the word "represent".  A PDP does not have to use one base policy 
for all requests.  The base policy it represents may be different for 
different requests.  It can also be logical and not concrete.

For example, based on a request, a PDP may obtain from a policy 
repository all the policies that apply to that request.  It then 
conceptually treats these policies, along with its configured base 
combining algorithm, as elements in a PolicySet that is its "base 
policy" for that particular request.
