No, you'll probably find that there's no speed difference at all (why
would there be?).  There will be a small size difference, but it will
be less exciting than you think -- the code to detect the prologue and 
load the module will make up much of the difference.  DTD validation
really doesn't require much extra code, and the code, of course, isn't 
triggered unless you're validating in the first place; doing the
well-formedness checks for legal characters can take up a lot of code, 
but you're supposed to do that anyway (I cheated with AElfred).

All the best,
