Hey Joe,

Yes, I like that much better than Assignment.  Still, I am not quite
satisfied with Association.  It's such a general term.  Can we come up with
a name that is more specific, e.g., 

    <Lot-Picker-Association picker="John" lot="1"/>  

Obviously, I really don't like that, but it is definitely more specific.

Good.  Should I use the term association instead of dependency?  Or, perhaps
there is a "physical dependency", and a "semantic association"?  /Roger
