htlatex mathml code loss

Question

I am using htlatex to convert a LaTeX to HTML.

I am writing the simple equation in latex document. This equation is converted my required MathML coding output 1.

Mathml Output 1:

<mml:math 
 xmlns="http://www.w3.org/1998/Math/MathML"  
display="block" mml:class="equation">
                    <mml:mi>&#x03B2;</mml:mi><mml:mrow><mml:mo mmlclass="MathClass-open">(</mml:mo><mml:mrow><mml:mi>G</mml:mi></mml:mrow><mml:mo mmlclass="MathClass-close">)</mml:mo></mml:mrow> <mml:mo mmlclass="MathClass-rel">&#x2265;</mml:mo> <mml:mi>&#x03B3;</mml:mi><mml:mrow><mml:mo mmlclass="MathClass-open">(</mml:mo><mml:mrow><mml:mi>F</mml:mi> <mml:mo mmlclass="MathClass-bin">&#x2229;</mml:mo> <mml:mi>L</mml:mi></mml:mrow><mml:mo mmlclass="MathClass-close">)</mml:mo></mml:mrow> <mml:mo mmlclass="MathClass-bin">+</mml:mo> <mml:mi>&#x03B3;</mml:mi><mml:mrow><mml:mo mmlclass="MathClass-open">(</mml:mo><mml:mrow><mml:msup><mml:mrow 
><mml:mi>F</mml:mi></mml:mrow><mml:mrow 
><mml:mi>c</mml:mi></mml:mrow></mml:msup 
> <mml:mo mmlclass="MathClass-bin">&#x2229;</mml:mo> <mml:mi>L</mml:mi></mml:mrow><mml:mo mmlclass="MathClass-close">)</mml:mo></mml:mrow><mml:mo mmlclass="MathClass-punc">.</mml:mo>
</mml:math>

The same equation is inserted plenty of math equation available and same configuration file is used. But the MathML coding is not converted properly. some of the tags are not implemented. The MathML coding output 2 below mentioned here

MathML coding output 2:

<mml:math 
 xmlns="http://www.w3.org/1998/Math/MathML"  
display="block" mml:class="equation">
                    &#x03B2;(G) &#x2265; &#x03B3;(F &#x2229; L) + &#x03B3;(<mml:msup><mml:mrow>F</mml:mrow><mml:mrow>c</mml:mrow></mml:msup> &#x2229; L).
</mml:math>

I compare the two MathML coding output 1 and 2 lot of coding are loss in my MathML output 2. For EX: (G) code convert O/P 1 is "<mml:mrow><mml:mo mmlclass="MathClass-open">(</mml:mo><mml:mrow><mml:mi>G</mml:mi></mml:mrow><mml:mo mmlclass="MathClass-close">)</mml:mo></mml:mrow>" But O/P two is converted just as (G). Lot of MathML coding missing.

I am using the same config file. But I don't understand the problem why the MathML code is Loss.

I can't load the full math version of the TeX file. So i load only MWE and CFG file for your reviews.

MWE:

\documentclass{book}

\usepackage[utf8]{inputenc}
\usepackage[numbers,compress]{natbib}
\usepackage{booktabs}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{upgreek}
\usepackage{hyperref}
\usepackage{graphics}
\usepackage{enumerate}

\begin{document}

\begin{equation*}
\beta(G)\geq \gamma(F\cap L)+ \gamma(F^{c}\cap L).
\end{equation*}

\end{document}

my cfg:

\Preamble{xhtml,mathml,NLM,-xtpipes,NoFonts,refcaption,DocBook}

\Configure{mathml}{mml:}
\Configure{MathClass}{0}{*}{<mml:mi>}{</mml:mi>}{}
\Configure{MathClass}{1}{*}{<mml:mo mmlclass="MathClass-op">}{</mml:mo>}{}

How to get the full MathML code for the Heavy Math TeX files. Please advise.
