Agreed.  If necessary, maybe you could move entities into their own
separate box, somewhat like has been done for data types.  I won't mind if
the W3C specifies a new way to provide the functionality that entities
provide today, but I'd very much like to see those capabilities separated
from the constraints end of schemas.
