26 <para>If you want type math directly in TeX notation in equations,
27 this parameter specifies notation used. Currently are supported two
28 values -- <literal>plain</literal> and <literal>latex</literal>. Empty
29 value means that you are not using TeX math at all.</para>
30
31 <para>Preferred way for including TeX alternative of math is inside of
32 <tag>textobject</tag> element. Eg.:</para>
33
34 <programlisting>&lt;inlineequation&gt;
35 &lt;inlinemediaobject&gt;
36 &lt;imageobject&gt;
37 &lt;imagedata fileref="eq1.gif"/&gt;
38 &lt;/imageobject&gt;
39 &lt;textobject&gt;&lt;phrase&gt;E=mc squared&lt;/phrase&gt;&lt;/textobject&gt;
40 &lt;textobject role="tex"&gt;&lt;phrase&gt;E=mc^2&lt;/phrase&gt;&lt;/textobject&gt;
41 &lt;/inlinemediaobject&gt;
42 &lt;/inlineequation&gt;</programlisting>
43
44 <para>If you are using <tag>graphic</tag> element, you can
45 store TeX inside <tag>alt</tag> element:</para>
46
47 <programlisting>&lt;inlineequation&gt;
48 &lt;alt role="tex"&gt;a^2+b^2=c^2&lt;/alt&gt;

51
52 <para>If you want use this feature, you should process your FO with
53 PassiveTeX, which only supports TeX math notation. When calling
54 stylsheet, don't forget to specify also
55 passivetex.extensions=1.</para>
56
57 <para>If you want equations in HTML, just process generated file
58 <filename>tex-math-equations.tex</filename> by TeX or LaTeX. Then run
59 dvi2bitmap program on result DVI file. You will get images for
60 equations in your document.</para>
61
62 <warning>
63   <para>This feature is useful for print/PDF output only if you
64     use the obsolete and now unsupported PassiveTeX XSL-FO
65     engine.</para>
