Re: [YANG] keyref

In the Ericsson DML we had something like

leaf my-if-status> {
   type instance-identifier {
     refers-to /if:interfaces/if:ifEntry/adminStatus;
   }
}

and in the XML

   <myIfStatus>/if:interfaces/if:ifEntry["if:ifIndex=2"]/adminStatus</myIfStatus>

This is quite simple, it works as a leafref as well, and works with multiple keys. refers-to 
restricts the kind of instance identifiers you can actually use. The actual XML value is 
somewhat more complicated, but I think the instance identifier format is quite intuitive even 
for people unfamiliar with XPATH.
