My last point wasn't very clear and TBH isn't well thought out. 

I was latching onto the <association> idea and musing that this could form the basis of a very useful service description: that an interface actually implemented or extended one or many other interfaces.

*I'm* not saying it.  I've been dissing it ever since the WG adopted it.

Too bad for you, under the current spec.  You can create a service with
another name (in the same namespace), but you can't implement a second
interface in the same service.

Completely lost me, sorry.
