Yes, as she stated up front. She wants to pull them together *in  
spite* of them being different.

"Service" is used differently in OWL-S and in WSDLland....a WSDL  
"service" can contain any number of completely unrelated operations.

That was the result of the conversion from WSDL, but it doesn't meet  
her needs.

Yes, but if you want to say something about all of them "at once",  
e.g., that they are offered by the same provider and that provider  
has a certain privacy policy, then it's a bit inconvenient. The  
choice trick is not the happiest, obviously, but I believe Jo was  
going for a "ServiceCollection" approach anyway and was just curious  
about how the Choice trick would work out.
