Yes, I also think that the XBEL DTD should be kept simple.

This all depends on which DTDs you have in mind. 

Some factors that come to my mind:

 o The similarity of the structure in the instance and the meta-DTD

 o Mapping between element content to element content is much easier that
mapping from element content to attribute values and vice versa (This is
not yet implemented in xmlarch, but will be soon).

 o Reordering is not possible (as far as I know).
