<para>If you want type math directly in TeX notation in equations,
this parameter specifies notation used. Currently are supported two
values -- <literal>plain</literal> and <literal>latex</literal>. Empty
value means that you are not using TeX math at all.</para>
<para>Preferred way for including TeX alternative of math is inside of
<tag>textobject</tag> element. Eg.:</para>
<programlisting><inlineequation>
<inlinemediaobject>
<imageobject>
<imagedata fileref="eq1.gif"/>
</imageobject>
<textobject><phrase>E=mc squared</phrase></textobject>
<textobject role="tex"><phrase>E=mc^2</phrase></textobject>
</inlinemediaobject>
</inlineequation></programlisting>
<para>If you are using <tag>graphic</tag> element, you can
store TeX inside <tag>alt</tag> element:</para>
<programlisting><inlineequation>
<alt role="tex">a^2+b^2=c^2</alt>
<graphic fileref="a2b2c2.gif"/>
</inlineequation></programlisting>
<para>If you want use this feature, you should process your FO with
PassiveTeX, which only supports TeX math notation. When calling
stylsheet, don't forget to specify also
passivetex.extensions=1.</para>
<para>If you want equations in HTML, just process generated file
<filename>tex-math-equations.tex</filename> by TeX or LaTeX. Then run
dvi2bitmap program on result DVI file. You will get images for
equations in your document.</para>
<warning>
<para>This feature is useful for print/PDF output only if you
use the obsolete and now unsupported PassiveTeX XSL-FO
engine.</para>
