Absolutely.

This is clearly an error. There are two DTDs for HTML, one called the
strict DTD and one called the transitional DTD. Obviously, this FORM
definition was taken from the strict DTD, although the documentation of
Nethtml says it implements the transitional DTD.

In the strict DTD, one must put a container into FORM to comply with the
standard, e.g. <FORM><P>....<INPUT>...</FORM>. This is not necessary in
the transitional DTD which is the type of DTD actually used in the WWW.

I have checked in the change. There is a similar error for BLOCKQUOTE.
