FYI - on July 25th, the WS-Addressing WG dropped [1] the WS-PAEPR's analogous feature for embedding WSDL in an EPR (Dropped Section 2.2 - Web Services Addressing 1.0 - Metadata [2]) because the feature did not meet the CR implementation bar.

Well, with the caveat s/public/open/ I agree.

Spec in order to understand the pretty simple use-case of attaching a
Policy directly to an EPR!

A related question - why do we allow WSDL to be directly attached to
EPRs?  Shouldn't all you MEX-heads have protested the inclusion of
wsa:Metadata at all?  It seems to me either we should have bitten the
bullet and made wsa:Metadata -> wsmex:Metadata, OR we should allow and
define both wsa:Metadata/wsdl:Description and wsa:Metadata/wsp:Policy.

Thanks,
