I think there is also a practical implication. In the case that two 
services implement the same interface AND have the same target resource, 
then they are alternatives. The client can pick the service that offers 
the most appropriate binding or endpoint.

Sorry for asking what likely is a trivial question, but :

So, for example,  a client sees a printer service which can print a 
to a printer (identified by a targetResource), and also sees a printer
management service which can manage the same targetResource.
I can't see at the moment how the client can utilize this information. 
a client now can set up a printer first before sending a document to print 
But wouldn't a client be able to do the same if there were  two services
descriptions available (printer and printer manager) but without a
@targetResource ?

Thanks !
