Re: [xacml] RE: Context Handler

Hi Ray,

I did not understand that. As far as I can see, when the PDP needs the 
"type" attribute, it can ask a PIP to provide it. The PIP has all 
attributes of the request available as key values. How is this different 
from  a REP? The available information seems to be the same in either 
case. What did I not get?

Best regards,
Erik
