Yes, it is HTML 4.01.

I'm using the "id" of the <title> element in JavaScript code, and it works 
fine, although it's not officially accepted in HTML 4.01.

It is in XHTML, but not in HTML 4.01, so apparently your document declares 

an HTML 4.01 doctype.

This is hardly a reason to move to XHTML, though. In which context would 
possibly want to use an id attribute on the <title> element? The element 
uniquely determinable anyway, since only one <title> element is allowed in 

The site you mention is not an authoritative reference, and it does not 
like a handy practical reference either. For example, they say "The title 
should be the first element found in the head", even though HTML syntax 
not impose such a restriction, and such placement can even be dangerous. 
you use a <meta> element to declare document encoding, then surely that 
should precede the <title> element if the latter contains any non-ASCII
