	It can contain the declaration itself, although HTML
	doesn't permit this.

	As the DTD cannot provide any semantics information
	other than by the user agent matching the public (or
	system identifier) againts a set of semantics rules, 
	it seems to me that it is a perfectly reasonable use of
	<!DOCTYPE to tell the user agent what semantics to apply
	to the data (or confirm that it is an unknown type).

	HTML does not need to have an <html> tag++ and documents whose
	first tag is <html> are not constrained to purport to be
	HTML as commonly understood.  The document type indentifier is
	needed to confirm for the second case, although the first case
	could be handled by parsing the DTD.

	++ the HTML element has 0 0 status.
