Umm ... sure, but then you have to preserve the external entities for 
the entity references to refer to ;-)

The kind of scenarios I had in mind were streaming transformations: 
stuff arrives on a wire, leaves on a wire, and we'd like to keep the 
amount of state that has to be held on the intermediary to a minimum. 
Here it really doesn't make much difference if that state is maintained 
as the content of external entities or if it's maintained internally to 
allow the subsequent generation of subtrees in the primary output.
