I am trying to summarize the comments/suggestions to the current version of
working group:

(1) Apply a different privacy restriction on different level of data in
WSDL. The Privacy element 
    applies to the transaction from the Web services consumer to the Web
service and cannot 
    be restrictied to a particular set of data. Two possible solutions are:
XML Schema annotations
    and XML extensions.
(2) Remove the rel='p3pv1' attribute at all because of using namespaces for
(3) Require defining an element included in the WSDL to indicate the WSDL
processor must follow 
     the rules of P3P: <my:Privacy wsdl:required=true'/>
(4) Define the privacy policy by both reference and inclusion.
(5) Bi-lateral privacy privacy and preferences: The current version only
indicates that the statements 
     are only applicable to the information received by the service, and not
the client interacting with
     the service.
(6) The extensibility model of WSDL allows to put P3P elements and
attributes in all sections of the
     description. It should include P3P POLICY elements in the WSDL at the
interface, operation, or 
     service level.
(7) Apply/reference more than one policy in a WSDL. In the first cut, there
should have a logical AND 
    in privacy policies described in different levels.
(8) WSDL, per decision on 20030703, dropped its extensibility using XML
Schema. This includes the 
     wsdl:globalExt definition. Remove the
substitutionGroup='wsdl:globalExt' declaration from the 
     definition of the privacy element.
(9) Have a mandatory soap extension containing a policy; the semantics of
the extension is: either 
    your policy is compatible with this one, or you must not process the
message. Section 4.5 needs 
    to be clarified

Special thanks to the contributors: Rigo, Hugo and Philippe!

I am looking froward to hear from WSDL and SOAP working group.
