DTD to be used.

\begin{description}

\item [http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd]

Declares a  FPI (Formal Public Identifier)
``-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN'' for XHTML+MathML. The DTD is broken
sine it contains a processing instruction
\verb!<?IS10744:arch xhtml ...>!  with a colon in the name. XML 
parsers don't allow it when namespaces are enabled. It carries 
revision id `xhtml-1,v 1.1 2000/10/31 19:52:09 davidc Exp'.

\item[http://www.w3.org/Math/DTD/mathml2/xhtml-math11-f.dtd]

Suggested by the MathML 
specification
 http://www.w3.org/TR/2003/REC-MathML2-20031021/appendixa.html.  However, the
DTD incorporates also SVG.  It shows revision id
`xhtml-math11-f.dtd,v 1.16 2003/11/04 13:14:35 davidc Exp'

\begin{verbatim}
\documentclass{article}
\begin{document}
$  \mbox{is right-continuous at } -r  $
\end{document}

I see the problematic space between

    is right-continuous at

and

    -r

but I don't understand it.  The mathml code currently has there

    <\a:mathml mrow><\a:mathml mtext>is right-continuous at</\a:mathml mtext></\a:mathml mrow>
    <\a:mathml mo>&#x2212;</\a:mathml mo><\a:mathml mi>r</\a:mathml mi>

Replacing mrow with mstyle doesn't make a difference. Removing
the mrow solves the problem of the extra space.

I introduced the above changes to the mathml and mozilla-mathml
configurations, respectively.

\section{Big, BIG, ....}

The 
\verb'\special{t4ht@[}...\special{t4ht@]}' gobble the enclosed stuff.
The external pair is provided as grouping mechanism for
sub/super-scripts cases like \verb'\bigl(...\bigr)^x' within dvimath
mode. The \verb'{\HCode{}}' is neded for creating content delimiters
\verb'.' delimiters like in \verb'$\bigl. a_b \bigr)$'; without that mathml 
gets something wrong there. 


\begin{verbatim}
 > There are some minor problems wit \bigl | corresponding to #x2223 in
 > Mozilla encoding
 > but I eliminted it by using \left | which turned to be a right solution.

The \big... macros decide the dimensions of the delimiters. As is the
case with \sum, also here I don't know how to transport the dimensions
to mozilla.

The \left...\right macros ask latex/mozilla to determine the
dimensions.
