    why not? it is conceivable that it would information that the requestor 
      does not--or should not--have that could be used for accessing 
    secondary information necessary to derive a decision. as you pointed out 
    earlier this falls into the realm of operational control, and as such is 
    beyond the XACML scope. still, it doesn't mean that XACML doesn't play a 
    role in each decision.
