Attaching Policies to EPRs

This issue was raised late at the f2f meeting in Burlington and closed so that we could get to last call.  I'm reopening it as a last call issue.

Attaching policies to WS-Addressing EPRs is likely to be a common metaphor in how WS-Policy is used.  The policy attachment framework should address this usecase.

WS-Policy Attachment

* Replace the second-to-last sentence in section 3.4 with the following:

The following example illustrates the use of this mechanism with an
EndpointReference domain expression (see section 3.4.2) for a deployed
endpoint as defined in Web Services Addressing [WS-Addressing Core]:

* Add new section as follows:

3.4.2 EndpointReference Domain Expression

This section defines a domain expression for identifying endpoints as
policy subjects for the external attachment mechanism. The following is
a pseudo-schema for the URI domain expression:

(01) <wsp:PolicyAttachment ... >
(02)   <wsp:AppliesTo>
(03)     <wsa:EndpointReference ... >...</wsa:EndpointReference> *
(04)   </wsp:AppliesTo>
(05)   ...
(06) </wsp:PolicyAttachment>

The following describes the EndpointReference domain expression element
listed in the pseudo-schema outlined above:

This element is a WS-Addressing EndpointReference, and references an
endpoint policy subject.

EndpointReference domain expressions are used to attach policies to
endpoint subjects (as defined in sec 4.1.2) identified by a
WS-Addressing EndpointReference [link to WSA].
