Ashok, We discussed this at the ws-addr call today and are waiting to get clarification from ws-policy WG on the phrase "... assertion will not be applied ...," as to its meaning. It is not clear, to at least some (many?) member of ws-addr wg, what it means. We decided to postpone a resolution on this (and related issue) till we get some direction/resolution from ws-policy wg. -Anish -- Ashok Malhotra wrote: > Here is the relevant text from the Policy Framework document: > > [Definition: A policy vocabulary is the set of all policy assertion types used in a policy.] ... When an assertion whose type is part of the policy's vocabulary is not included in a policy alternative, the policy alternative without the assertion type indicates that the assertion will not be applied in the context of the attached policy subject. > > All the best, Ashok >> -----Original Message----- >> From: public-ws-addressing-request@w3.org [mailto:public-ws-addressing- >> request@w3.org] On Behalf Of Anish Karmarkar >> Sent: Monday, April 16, 2007 9:56 AM >> To: public-ws-addressing@w3.org >> Subject: Policy alternatives, negation, [Non]AnonResponse assertion and >> the none URI >> >> >> There is view among the WS-Policy wonks (not sure how widely accepted >> this is or whether the WS-Policy specs explicitly calls this out) that >> when there are alternatives present and the selected alternative does >> not contain an assertion X but another alternative does, then the effect >> of such a selection consists of negation of X. >> >> We have two assertions AnonResponse and NonAnonResponse assertions.
