In thinking more about this one... I'm not sure it makes a lot of sense to say which operations are required vs optional in both the Compliance section and section where each op is defined. The optionality of each op is really not any more special than any other requirement in the spec. And since the Compliance section already says: An implementation is not compliant with this specification if it fails to satisfy one or more of the MUST or REQUIRED level requirements defined herein. I don't see the value in calling out one MUST over another. To that end, I propose that we tweak the start of each section that defines an op/msg. Using Transfer Get as an example, it current start with: 3.1 Get This specification defines one Web service operation (Get) for fetching a one-time snapshot of the representation of a resource. We could change it to be: 3.1 Get This specification defines one Web service operation (Get) for fetching a one-time snapshot of the representation of a resource. This operation MUST be supported by compliant implementations. And Put, which would be optional, would look like: 3.2 Put This specification defines one Web service operation (Put) for updating a resource by providing a replacement representation. This operation MAY be supported by compliant implementations. And the table would be: WS-Eventing: Subscribe Required Renew Required GetStatus Required Unsubscribe Required SubscriptionEnd Optional WS-Enumeration: Enumerate Required Pull Required Renew Required GetStatus Required Release Required EnumerationEnd Optional WS-MEX: GetMetadata Optional WS-Transfer: Get Required Put Optional Delete Optional Create Optional 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.

An event source MAY send SubscriptionEnd message to an endpoint that supports SubscriptionEnd operation, if reference to such an endpoint is supplied when the subscription was created. An Subscription manager endpoint MUST support Renew, GetStatus, and Unsubscribe operations. An endpoint that supports SubscriptionEnd portType, if a reference to such an endpoint is supplied when the subscription was created, MUST support SubscriptionEnd operation. An event subscriber MAY use Subscribe, Renew, GetStatus, and Unsubscribe operations. Thanks.

Here is a suggested text for WS-Eventing. The same pattern can be applied for other specifications. [1] Proposal for WS-Eventing Add to Section 3.5 Compliance: Subscribe, Renew, and Unsubscribe operations defined in this specification MUST be supported by compliant implementations. GetStatus and SubscriptionEnd operations defined in this specification are optional and MAY be supported by compliant implementations.
