Let me try to give a better explanation why I am uncomfortable with both
Assignment and Association.  Suppose that Association is used:

<Association picker="John" lot="1"/>

Consider the task of stating the relationship between the Picker and the
Lot.  How would you verbalize it?

   "The Picker is associated with the Lot"

What does that mean?  It's very vague, to the point of being meaningless.  I
want the relationship to be more specific, e.g.,

   "The Picker is located on the Lot"

Perhaps, then, I should use this:

<LocatedOn picker="John" lot="1"/>

Hmm, that doesn't seem right either.  Suggestions?  /Roger
