Yes, but again this situation is quite simple. If all you needed to do 
was move pickers to different lots. So pickers can be assigned to 
different lots. What if you want to track their time spent on the lots:

<lot id="1">
   <picker ref="John">
     <timecard start="2005-01-29T12:00:00" end="2005-01-29T13:00:00"/>
   </picker>
</lot>
<lot id="2">
   <picker ref="John">
     <timecard start="2005-01-29T13:00:15" end="2005-01-29T14:00:00"/>
   </picker>
</lot>

Seems to be exactly about coupling, doesn't it? Maybe I should read more 
definitions...
