I think that's entirely up to your implementation.
My suggestion, which you're more than free to ignore, is the following:
* If the service relates directly to the data in the SRW service, then
make it an extension. To have a separate service that makes use of the
same data in the context of IR seems a waste of effort.
* If the service could be used in conjunction with services other than
just the one SRW/U instance, then make it a new web service or operation.
To apply it to your example:
1. Web service: The web service offers suggestions or synonyms to any
word, which may or may not be in the indexes for the SRW instance.
2. Extension: The extension allows the server to return suggestions
and/or synonyms, along with the number of hits they'll generate, to a zero
Does that make sense?
