You seem to be mixing authoring requirements and implementation 
requirements. The implementation requirements for handling <!doctype> 
lines in HTML5 will almost certainly be identical to those for treating 
comments (I haven't really thought about it yet).

Well again it depends if you are asking about authoring or implementation 
requirements. For implementations there are no requirements here.
