  I think this is where the SGML distinction between an "entity" and a 
file makes a lot of sense.  Each XML entity can be exactly one
instance, but an entity manager can be used to access multiple
entities in a single file.  Each entity can be individually retrieved
from the file using the entity manager.  As expected, this is only
useful (as far as allowing other tools to work directly on our files)
if our entity manager behaves the same way as theirs does.  Which
means, at least for now, one file === one entity.
  I can live with that.
