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

>From Progress' POV, it's more about not wanting to pull in Yet Another
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,
