I would say that we don't retain it, since the policy assertions are
accessible through the {policy} property defined by the WS-Policy
attachment specification. Of course, we could always define our policy
assertions to affect the WSDL Component Model if it is part of the policy
alternative in effect, but this is not a current practice as far as I
know. I can see advantages for implementing it that way though.

Yes, except that it should be recast to show the effect of the policy
assertions, if the policy assertion is part of the policy alternative in
effect.

I forgot about the SOAP module definition. We avoided the nightmare of the
combination of UsingAddressing and Addressing policy assertion but we
still have it with the SOAP module... I didn't see much support for this
in the past so my opinion is that it should be remove unless someone can
come up with a good story of how it combines with the policy alternatives.
