I might be being dim here, but I don't see how that is possible.
Messages for different applications will have arbitrary structure and
content. I accept that within the scope of an application or service the
contents of a message can be mapped to some logical operation (within
the scope of the service) but I don't see how a public spec would help

But I do agree that the operation name is implicit not explicit - though
I maintain it is implicit in the message and resolved by the Web

This situation never occurs though does it? I advertise some contract
that says "Send me a 'WeatherUpdate' message" and since I advertised
that contract it would be ridiculous of me to then not understand those
