  That's IMHO a limitation of the original SAx interface as provided
by expat, one can return only attribute strings. Since i want to
be able to generate entity ref within attribute values in the DOM tree
I have to pass the value as parsed and do the entity lookup later on.
Check the attribute() function in the SAX.c module.
  I think that if you ask for automatic entity replacement, then
in that case you will get substituted values.
  I didn't want to bypass the SAX layer when implementing the DOM
tree so I had to make a couple of decisions like this.
