The bugs you reported are fixed in v98.1p3
(available at the Darmstadt repository).

The {trivlist} environment is now implemented.
It hadn't been done before since it's accepted usage was not clear.
Notice that this use of {trivlist}...

...does not agree with the description of {trivlist} in the Reference
section C.6.3 of the "blue book".
That description does not seem to allow any material
before the first \item .
List-like environments in LaTeX2HTML had been built upon this assumption
of no preceding material, even if just style-changes.
Now the new &do_env_trivlist allows for this possibility.
Indeed it collects all such material and applies it
before each \item separately.
This is necessary to get HTML tags nested correctly
within the <DL> description-list structure.
Unfortunately, the zero margins criterion cannot be met,
since the browser itself puts in such margins.

Fixed.

\begingroup ... \endgroup is now implemented as follows:
Internally is created the effect of:
\newcommand{\begingroup}{\begin{tex2html_begingroup}}
\newcommand{\endgroup}{\end{tex2html_begingroup}}
and similarly
\newcommand{\bgroup}{\begin{tex2html_bgroup}}
\newcommand{\egroup}{\end{tex2html_bgroup}}
Now, after newcommand replacements have been made and braces are numbered,
the normal &translate_environments procedure will ensure the correct
groupings and tag-nestings.
Thanks Sven, for a very useful contribution.

Ross Moore
