Now there's a good question.  At the moment, we have no mechanism aside
from a prominent notice on the website/marketing-material/tech-doc saying

"output from the MegaSoft XML-frobnosticator v7.4 in general uses
 external entities, and thus a validating processor is required to
 process it"


"output from the MicroCorp XML-depullulizer v0.3 does not use
 external entities and may be processed correctly by a non-validating
 XML processor"

David Singer of IBM at one time suggested that we bless another 
PI or something in the XML declaration, saying

<?xml version="1.0" extentities="no" ?>

which is an assertion that no external entities are used. -Tim
