A comment before the doctype has equal status as lack of doctype or an 
incorrect doctype. Hence, conformance checkers will flag such documents as 
non-conforming, and the syntax section should only allow things that will 
pass conformance checking.

What are those reasons?

I don't want to deny authors anything, I just want the syntax section and 
the parsing section to agree. If there really are valid reasons to have 
comments before the doctype then the parsing section should change instead 
of the syntax section.
