White-space and SGML comments are ignored by HTML. The first TAG has to be
<HTML...> but I guess that before this tag an unlimited amount of white-space
and SGML-comment may occur.

This explains at least why they use this <!DOCTYPE header to specify the
HTML version. Technically this is SGML comment and therefore shouldn't break
exisiting (HTML 1.x or so) applications.
