Hi Umit,

Thank you for continuing the conversation. Yesterday, Ashok posted a new
proposal [1] to resolve 3557. I think the best way to move forward on
this issue is to review the new proposal. I'll do that very soon.

You are right to indicate that the current xsd indicates that the
content of the wsp:AppliesTo is xs:any, but I am not following why you
are bringing this up. 

The specification currently written as in second paragraph of the
Attachment document also acknowledges the utility of IRIs. Just to
quote:

{This element has three components: the policy scope of the attachment,
the policy expressions being bound, and optional security information.
The policy scope of the attachment is defined using one or more
extensible domain expressions that identify policy subjects, typically
using IRIs.
}

The keyword is "using". As you indicate, one would need a wrapper
element in order to include an IRI, but this does not prevent using
IRIs. 

The proposed example text for "using" IRIs are not inconsistent with the
current editor's draft.

Just to comment on WSDL, the policy subjects and policy scopes that
apply to WSDL references would exactly those that are currently
specified in Section 4 of the specification. Nothing new is invented
here. You can think of it as alternative syntax that conforms to the
same attachment points only expressed via a referencing mechanism
instead. 

HTH,
