[..]

To be complete about a WSDL description of addressing, I forgot to
mention that the message information properties should be given a URI
and flagged as properties of this feature. Some of those will be set
at run time while others (e.g. reference properties, if I understand
them correctly) will be described in the WSDL.

Please note that this is not a WSDL 2.0 F&P versus content model
discussion that I want to start here, which is a topic that belongs to
the Web Services Description Working Group. Giving URIs to those
properties just identifies them so that they can be easily described
and talked about. I believe that this solution covers our bases for
whatever the Web Services Description Working Group ends up with in
this space.
