Re: [xacml] another small time/date issue

this is my point. the only 'requirement' that we need be concerned with 
is the set of subject/action/resource inputs for a specfic decision. as 
i poisted in my first note, this does not exclude the [pXp] introducing 
attributes in a multistep process. XACML simply doesn't address how this 
is done (the point that i *think* you are trying to make ;o), it treats 
each decision as a unique transaction.
