Actually this may be much simpler to implement than we thought. I
modified the code so that it now uses the new feature introduced by
AXIOM-399. This means that the OMDataSource is expanded when the name
of the element is first requested. I would expect that this occurs in
the code that dispatches to the service operation. At that point the
service should already be set in the message context. If that is
correct, then this means that at the time the OMDataSource is
expanded, the service to which the request is dispatched is already
known. We could then get the namespace mappings from a service
parameter that the user must configure in services.xml.
