HTML 4.01 was published by the W3C after it took over HTML development from 
the IETF/IESG [RFC2854].  The W3C works like an international 
standardization organization. [W3CAbout]  W3C Recommendations are called by 
them (ibid.) and considered by many people “Web standards”:

And the HTML 4.01 Specification, which had only achieved Recommendation 
status in 1999 because it was formally approved by the W3C Director and
Membership [W3CProc], is not?

I think the fact that you have to borrow arguments from other people in 
order to have an argument *at all* is indication that you have not thought 
this through.

The argument made there is flawed in the first place because a *declaration* 
is exactly that: a means to say (*declare*) “this is (supposed to be) a 
$SOMETHING”.  A *DOCTYPE* declaration says/declares “this is (supposed to 
be) a $SOMETHING *document*”, a *document* of a certain *type*.  The 
syntactical restrictions thus enforced (and not enforced) implicitly define 
the semantics (meaning) of the $SOMETHING; what the $SOMETHING *is*, what it 
*means*.  Hence DOCTYPE (Document *Type*) Declaration.  A type is a 
classification, a means to ascribe common properties to different objects.

The argument made there does not apply to HTML in particular because Valid 
HTML, at least in version 4.01, *excludes* the SGML feature (internal 
subset) that could put into doubt the intended type of a document.

See also:

(contains the full text partially quoted above)

<http://www.w3.org/TR/2010/REC-MathML3-20101021/appendixa.html#parsing.doctype>

etc.

This shows that a DOCTYPE declaration is in practice, at least for Web 
documents, much more than just a hint or relevant to syntax.  If the 
declaration and the content does not match, you are asking for trouble.

Compare:
