Correct, insofar as HTML versions 1, 2.1, and 2.2 are never
used anymore, having been superseded long ago by HTML 3.2 and 4.x .
Similarly 3.1 is out-dated, implementing <MATH> tags that
never got universal acceptance.

Yeah, that was the idea.
OK, so there needs to be a small patch to get the DOCTYPE correct.

The same trick was used with 3_1 really being 3.01 (I think).
For compatibility with any existing documents or scripts calling
LaTeX2HTML, it would be best to catch 4_1 and make it 4.01
where needed, as well as stopping the rounding.
There is no future compatibility problem, as the W3C have effectively
frozen HTML at 4.01 --- as far as I can recall.
Future development is in XHTML and XML.
