Excuse my intervention...

The modification descriptiors were introduced by Uwe Ostermeier to 
handle the versioning and cataloging stuff. I'm not an expert in that 
field, but in my understanding the modification descriptors are more 
general and your case is a subset that could be handled with them. As a 
developer, I would still prefer one concept, because it's easier to 
adapt. Sufficiently fundamental cases are always a shaky discrimination 
to differ two concepts for future implementation decisions.
