Hi,<br>
  I'd like to report a possible bug in tex4ht.<br>
<br>
If I compile the file<br>
<br>
\documentclass{article}<br>
\usepackage{amsmath}<br>
\begin{document}<br>
\begin{equation*}<br>
x=1<br>
\end{equation*}<br>
\end{document}<br>
<br>
with<br>
htlatex a.tex "xhtml,docbook-mml" " -cunihtf" "-cdocbk"<br>
<br>
I obtain the following error message:<br>
...<br>
! Extra }, or forgotten \endgroup.<br>
\endequation* ...me b:equation*\endcsname \egroup<br>
<br>
l.6 \end{equation*}<br></blockquote><div><br>Kindly add the following either in your custom *.cfg or just after \begin{document} of your document:<br><br>\Configure{equation*}<br>  {\ifvmode \IgnorePar\fi   \EndP<br>   \HCode{<blockquote role="equation">}%<br>
