Is there a notion of "finality" when it comes to box widgets? 
Specifically, are there widgets for which it makes no sense to place 
other widgets inside of them (bevel comes to mind), and if so, is this 
enforced anywhere? Also, are there widgets that should only contain a 
restricted list of other widget types?
