I am not surprised that there are not many of those out there. What
surprises me is that there are any at all. How does a client application
figures out the semantics of an interface it has never encountered before?
It has to be something about very well delimited domains and very well
defined naming conventions for verbs and parameters (or very familiar
namespaces) ...
