Good point - so representation-wise you would also need some work for
the workflow designer to select the right one - like deeper folders
within the WSDL in the Service Panel, and showing more information
such as descriptions from the WSDL file.

We still have not treated either multiple bindings for the same
operation/action - which in theory you could also do in the WSDL -
those would then be between equivalent service endpoints - so Taverna
should probably try each of them in order on failure - but keep a
record of which one was 'really' used.
