Proposal Number 3 ============== 1) WS-Transfer (and equivalent in other specs) Keep: - - - - - An endpoint MAY indicate that it supports WS-Transfer, or its features, by including the WS-Transfer Policy assertion within its WSDL. By doing so the endpoint is indicating that the corresponding WS-Transfer operations are supported by that endpoint even though they do not explicitly appear in its WSDL. But drop: - - - - - - - - (i.e. the WSDL that MAY be retrievable by using a WS-MetadataExchange GetMetadata with a Dialect IRI of http://schemas.xmlsoap.org/wsdl/). An endpoint MAY choose to expose the WS-Transfer WSDL by using the following WS-MetadataExchange Dialect: Dialect IRI @Identifier value ======================================================== http://www.w3.org/2009/02/ws-tra/TransferWSDL Not defined The WS-Transfer WSDL can be annotated to indicate any endpoint specific metadata that might be needed by clients interacting with this service. For example, the WSDL MAY have policy assertions that indicate a particular security mechanism used to protect the WS-Transfer operations supported by this endpoint. 2) To the end of the 'keep' part above, add: - - - - The WS-Transfer WSDL containing the operations indicated by the TransferResource Assertion MAY be exposed as described in WS-MetadataExchange [WS-Mex] section 9 . This WS-Transfer WSDL can be annotated to indicate any endpoint specific metadata that might be needed by clients interacting with this service. For example, the WSDL MAY have policy assertions that indicate a particular security mechanism used to protect the WS-Transfer operations supported by this endpoint. 3) WS-MetadataExchange Add section 9 : - - - - - - - - - - - 9. Exposing WSDL for Operations Implicitly Defined by a Policy Assertion An endpoint MAY indicate that it supports a specific feature by including the feature?s policy assertion within its WSDL. By doing so, the endpoint is indicating that corresponding operations (if any) are supported by that endpoint even though they do not explicitly appear in its WSDL. An example of this is an endpoint that indicates the use of WS-Transfer [WS-Transfer] by the use of the wstrp:TransferResource WS-Policy [WS-Policy] assertion. An endpoint MAY choose to expose the WSDL of the policy defined feature by using the http://schemas.xmlsoap.org/wsdl/ dialect and the dialect identifier of the target namespace of the feature.

For example, the WSDL can have policy assertions that indicate a particular security mechanism used to protect the feature's operations supported by this endpoint. When a Feature WSDL does not provide a concrete endpoint, the consumer MUST use the concrete aspects of the endpoint's WSDL. thanks -Doug ______________________________________________________ STSM | Standards Architect | IBM Software Group (919) 254-6905 | IBM 444-6905 | dug@us.ibm.com The more I'm around some people, the more I like my dog.

" Hi Ram, Thank you for your comments. I agree with the editorial changes - they make the text clearer. However, I don't think we should remove this: > "If the WSDL includes a wsdl:service element then the endpoint indicated within the WSDL MUST be used for the operations defined by this WSDL document." The intention was to state something more than the WSDL semantics - namely that the feature's WSDL may indicate that the feature is supported at a different endpoint. Perhaps this isn't clear and it could be re-written like this?: > "If a Feature WSDL is abstract, then the endpoint of the Endpoint WSDL MUST be used for the feature operations. If a Feature WSDL defines a concrete endpoint, then this endpoint MUST be used for the feature operations." On a separate point, I also noticed that the following text in brackets below is incorrect as it also requires @Identifier=tns. I think we should consider simply removing it in order to simplify the text. > ... (i.e. the WSDL that MAY be retrievable by using a WS-MetadataExchange GetMetadata with a Dialect IRI of http://schemas.xmlsoap.org/wsdl/). It is quite confusing to see where we are with the proposal, so below is an updated proposal which (I think) reflects your suggested changes and my suggested amendments below. The changes from the first proposal are highlighted.

" Hi Katy, I have a few editorial comments. Ø An endpoint MAY indicate support for a specific feature (e.g. a specification) and the corresponding feature operations by inclusion of a policy assertion within its WSDL. In such a case, the feature's operations do not explicitly appear in the endpoint's WSDL. For consistency across all three parts of the proposal, I suggest rephrasing the above as follows: ?An endpoint MAY indicate that it supports a specific feature by including the feature?s policy assertion within its WSDL. By doing so, the endpoint is indicating that corresponding operations (if any) are supported by that endpoint even though they do not explicitly appear in its WSDL?. Ø An example of this is an endpoint indicating its conformation to the WS-Transfer [WS-Transfer] definition s/an endpoint indicating its conformation to the WS-Transfer/an endpoint that indicates the use of WS-Transfer/ Ø If the WSDL includes a wsdl:service element then the endpoint indicated within the WSDL MUST be used for the operations defined by this WSDL document. Since this text restates the normal WSDL semantics, I suggest removing this. Thanks.
