Hi Jean-Paul, Possibly it was me who mentioned something that might have been interpreted as a fourth option . I was basically asking a question whether existing parameter mechanisms had been looked at such as the <CombinerParameters> or the parameters in the higher order bag functions. It seemed to me that the basic problem was to evaluate the policy w a variety of values tested for a single attr value in the logic. It seems to me that is the same type of operation that takes place in the items I mentioned, except those may be more restrictive than you were looking for, or they may not work at all - I have not had time to really study the problem in enough depth, which is why I posed it as a question rather than a suggestion.

https://wiki.oasis-open.org/xacml/Policy%20Template%20Profile , and more specifically the page describing the 3 options discussed today on the call
https://wiki.oasis-open.org/xacml/Policy%20Template%20Syntactic%20Options ), and update the Syntactic option page with the option 4 that you came up with? This will be really useful so we can re-activate the discussion by Email thread. At the same time I will add the “static vs dynamic” considerations in the Pros-Cons sections of each option, as Hal suggested, I believe. Thanks, Jean-Paul Buu-Sao
