All, Another approach has been preliminarily discussed during the initial f2f discussions of issue 4235. Rather than simply add a note, as originally proposed, change the specific starting point for the normal form algorithm to be the EII of the root of the policy expression to be normalized. Roughly, this would involve: <PaulC> Proposal: <PaulC> 1. Start with the Element Information Item E (as defined in the XML Information Set [XML Information Set]) of the policy expression. The [namespace name] of E is always "http://www.w3.org/@@@@/@@/ws-policy". In the base case, the [local name] property of E is "Policy"; in the recursive case, the [local name] property of E is "Policy", "ExactlyOne", or "All". <PaulC> 2. and change "D" to "E" in subsequent steps. It has also been suggested by Umit that we could do both. e.g. make the changes as outlined above, and add a corresponding note that indicates that you extract the policy expression from its element context and treat it separately. Some also observed that we needed to possibly specify how you find the "root" of the policy expression. We will pick up discussion from this point during tomorrow's f2f discussion after we address the wsdl1.1 identifiers issues.
