Hey Robert,

>I would hate to have transform this... 

Suppose that the purpose of your transformation was to move Picker John onto
another Lot. (For example, a stylesheet that models the movement of Pickers
on a Vineyard)  Wouldn't this form support such a "movement transformation"
beautifully?  

Simply locate:

    Assignment/@picker="John"

And then change:

    @lot

But this is getting off the topic: what is coupling?  /Roger
