Yes this makes sense, although I would have thought that there would be only 1 Service Impl backing different EP's and so the state would be applicable to the service itself, rather than the EP fronting it. But I see your point.

  | We were saying that this type of more advanced lookup might be part of a future release.  JAXR has the ideas of Service "Classification" and "Concept" and I'd guess that these could be used as parameters to a lookup.  In the mean time though, the client/user can manually filter the Service list returned from getServices by manually interpretting the Classification/Concept settings on each Service.

Ah ok!

Sorry my mistake. For a validation service that requires the client to pass in xml, the client would need to pass in a reference to an XSD aswell, that the xml must adhere to. So my point above is invalid.


What i think I was leaning to was, will we use the registry to hold objects other than Services, such as XSDs and XSLTs that are application resources that need to be accessed centrally? Thereby implying can a Service also be classed as an Application Resource ?
