It seems like a very interesting proposal!  (And cutting down on 
maintenance burden is a *big win*.)

In fact, the only "problem" I can think of with this solution is that 
I'll be adding:

<downgrade inherit="upgrade"/>

To all of my packages.  (I wonder if XSLT can help this case?  Templates 
really are perfect for this kind of "boilerplate" that you really 
shouldn't have to manage everywhere.)

The inherit attribute should be the easy part, though.
