Re: proposal for restricting a service to a single interface

Sergey,

Yes, the default value for @xpath is "." which selects the entire part. 
That's in the proposal.

We could also make @part optional if there was exactly one part in the 
message.

Making the binding optional is much more problematic since many bindings 
can be applied to an interface and there is not necessarily even a 
<service> element to list the bindings that are provided. I would 
therefore maintain that the @binding is required.
