Thanks for the clarification.  That's what I thought I was responding to in 
the first place :-)

Some seemed to be saying that it is a Bad Thing to require those extra 
steps in order to parse arbitrary, legal XML.  I personally have no problem 
with it -- whether it be a bug or a feature -- simply because it *seems* to 
reflect the reality that I repeatedly hear about: one can make significant 
optimizations in an implementation if there is some understanding that 
there will be no entities to expand.  The *user* chooses whether to be 
liberal at some cost (in performance, in vulerability to the billion laughs 
attack, or whatever), or conservative.
