Well, how about just eliminating the <Restriction> brackets, which as 
far as I can see serve no useful purpose:

<restrictedBy>
    <hasValue>

and eliminating </Restriction> at the other end? We know this is a 
restriction since it follows <restrictedBy>, so why do we have to say 
so again?

But its just as much wasted typing.
