Hi Mike:
In addition to the lifecycle issues that Rich has raised, I would like
to bring up a few high-level questions
re. you proposal for issue 15.
1. We can extend the policySet syntax to accommodate policy attachment
but we also need a file format.
This is for the file that contains the policySets and can be included in
a contribution.
2. I raised the usecase for corporate policies which, under the existing
specification could be merely included at some
high level and then pulled in as needed. Under the new proposal this
needs a bit more work. I would like to see
the details for this fleshed out.
3. Policies on interfaces
a. interface.wsdl is identified by a URI that points to a definitions
file. If we want to attach policies to individual interface
elements such as a operation or a message, we should use the WSDL
fragment identifier syntax as used by binding.ws.
b. A common usecase may be "apply this policy to this binding and this
interface". This would require an XPath function
that identifies a wsdl interface which has as a sibling a particular
binding. This is not a simple XPath function to
write. We need an existence proof.
c. In the above usecase, what does the policy get attached to? The
binding or the interface element or some combination?
If it is attached to the interface it applies to all sibling bindings,
which may not be what we want.
You will recall that this is the reason Mike Rowley wanted to munge the
domain interface in unnatural ways. But we still
need to solve the problem.
All the best, Ashok
