Bug report: HTML validator

When validating both with 4.01 transitional and 4.01 strict, a missing
         </body>
         </html>

at the end of the file does NOT produce any errors... Seems like that is a 
pretty basic error?

But for some reason, 4.01 Frameset DOES produce the expected error!! 
(although that is clearly not the validator you want to use) i.e.

Line 97, column 9: "HTML" not finished but document ended
