What I'm trying to understand is... if you're OK for having the "only 
allow 1 doctype node" special-case, what makes it more complicated to 
also check that it's before the element?  I believe you that it does, 
but just trying to understand why.

I could possibly live with one doctype allowed to be after the element; 
the other ones seem like they violate too many invariants people might 
be depending on.
