My understanding is that policy statements made in the policy bucket
(i.e. as standalone statements not attached to a WSDL description)
would apply to the [service endpoint] endpoint. However, I don't think
that our spec can itself go in that kind of detail, but rather that a
policy spec should probably have a section about how to attach policy
statements in an EPR and what that means.

Statements attached to WSDL may indeed refine or contradict those
other policy statements made about [service endpoint]. However, once
again, the reconciliation and combination rules would be the
responsibility of the policy language.

I think that we don't need to be specific about how to use a policy
language that we currently don't have. The same way we've done a WSDL
binding for Addressing, we'll probably have to write a policy binding
for Addressing. A metadata bucket seems generic enough to support what
we need here.

Cheers,
