Apologies, I haven't seen this example. If you need to associate 
multiple endpoints from different WSDLs, then I can see why you'd choose 
a linking mechanism. But the use case is not clear to me.

To be clearer, my point was there's logically a single containing 
entity. You can call it a resource or a service or something else. But
