Hi Ron, prepare to be pleasantly surprised.  There is a standard feature in
SAX called "http://xml.org/sax/features/external-parameter-entities", which
prevents the parser from reading any external entities - including the
external DTD subset.

Not all SAX parsers support this feature, but many do (ours included).
