Subject: Re: [xacml] another small time/date issue
unless i read this incorrectly it seems that these are not mutually
exclusive positions: a request goes to a single PDP whereby information
may be added/enhanced for downstream decision requests. in this
scenario, attributes may be change in the life span of an aggregate of
decisions, but they remain 'explicit' (static) for each decision context.
true, this may lend itself to unanticipated decisions in the macro
sense, but each localized decison--that which i believe XACML is
intended to cover--will resolve deterministically.
