So I may address this issue further on the Xerces mailing list as I 
can see the "empty.dtd" gets read, first by registering a SAX 
LexicalHandler and observing the start/endEntity events, then by 
declaring:

<!ENTITY fu "foo">

And replacing "foo" with "&fu;" (w/o the quotes) in the original 
example.
