In the spirit of non-productivity, I'll note that we get the following 
from Roget's (emphs. added):
	http://thesaurus.reference.com/search?q=operation
-------------
Entry:    operation

Function:    noun

Definition:    working

Synonyms:   
act, action, activity, affair, agency, application, ball game, bit, 
carrying on, conveyance, course, deal, deed, doing, effect, effort, 
employment, engagement, enterprise, exercise, exercising, exertion, 
exploitation, force, handiwork, happening, influence, instrumentality, 
labor, manipulation, motion, movement, performance, play, procedure, 
proceeding, process, progress, progression, scene, ****service****, 
transaction, transference, trip, undertaking, use, work, workmanship

Concept:    ****usefulness****
------------

More seriously, if the problem lies in what we implicitly suggest to 
developers, then the real solution is to explicitly contradict the 
implicit suggestion. The pain of leaving the explicit contradiction of 
an implicit suggestion must be weighed against Yet Another Somewhat 
Gratuitious Name Change.

I suggest, implicity, something like the following text:

"To some, the term 'operation' might implicity suggest that an 
operation describes something more than a message exchange. In WSDL, 
nothing could be further from the case. That a particular operation 
gets mapped, in some application, to, say, a method invocation is 
*never* said, suggested, implied, or endorsed by the existence of a 
WSDL operation component. Don't go there."

Cheers,
Bijan Parsia.
