So in other words, in the flattened tree nodes 4 and 5 can't be repositioned to 
different <content> insertion points in the binding attached to A (since it's 
the <content> node that's a child of A being repositioned, you can't filter 4 
and 5 into different insertion points).  Is that correct?

Perhaps the problem is that as I read I'm mapping onto the Mozilla XBL 
implementation, looking for the differences, and trying to understand them...
