document vs non-document entity (was Re: CORBA's not boring yet. / XML in an OS?)

One (serious) issue that imediately arises out of my XML überdocument system
is that there is a difference in XML between the document entity and other
entities: the existence of the prolog.

If an XML document has a empty prolog, there is no problem because an XML
document entity with an empty prolog is a legal external parsed entity.
However, the moment you have an XML declaration or document type
declaration, the entity can no longer act as an external parsed entity.
