This has an application specific meaning, and so cannot define it at this
level. WSDL is a language for defining message exchanges that a service will
particate in, nothing more, nothing less. If you need to add additional
semantics to the exchange of those messages, then that's for the application
(or more likely some application-level framework) to deal with.

To paraphrase, "The first thing you need to understand is that there is no
operation."
