Yes.

Even in addition to that, though it's probably not what you want :)

Well, there's no trouble at all in putting them in *one file*. That's  
easy. If you want to have a single "Service" object "represent" three  
distinct bits of functionality, there are, as I said, a number of  
ways to do it. For one, you could use a Choice composite process.  
While in a sense it "composes them into one composite process" it  
also models what you're asking for...a service that can provide any  
of three distinct bits of functionality.

I would say that this is the canonical way. But, just because I said  
so :) Well, other than having a file with three service objects in  
it, which, of course, could share properties.

You could "abuse" simple processes :)

You could make an object "service collection" that hung certain  
metadata off the grouping. This would be an extension, of course.
