Just to make sure everyone else is as sick of this minutia as I am I 
thought I would take this a step further. Consider:

<!DOCTYPE doc SYSTEM "doc5.dtd">

<!ELEMENT doc (foo)>
<!ENTITY % pe_foo "<foo>">
<!ENITY gen_foo "&#37;pe_foo;</foo>">

Now, the replacement text for gen_foo after it is scanned becomes:


It is obvious that the reference to gen_foo would violate WFness. The 
question is: is this a PE inside the DTD and inside content-- thus 
violating "Well-formedness constraint: In DTD" while simultaneously 
being "recognized"? : )

All the best,
Jeff Rafter
