Subject: Re: [sca-policy] [ISSUE 15] External attachment - Alternative Proposal
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.
