Docbook + MathML .. html output ? PDF problem

[Marc Baaden <baaden@smplinux.de>]

Hi (again),

I have tried to make a docbook document using MathML (following a
tutorial). This seems to work rather fine, *but*

- although rendering through passivetex produces fine output, some
  equations are not rendered correctly. Eg a sum over i does show the
  i not below the sum but next to it, although verification of the
  MathML code with amaya confirms that it should be below.

- <inlineequation> does not seem to work with those equations

- the html output does not show any equations, but the raw mathml code.
  is there a way around this. Also given that only very few browsers
  understand mathml, is it eg possible to rather generate images to
  include for html ?

Maybe it is the way I included the mathml, so here is what I use:
Main document goes

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN"
"http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd" [

<!ENTITY % MATHML.prefixed "INCLUDE">
<!ENTITY % MATHML.prefix "mml">
<!ENTITY % equation.content "(alt?, (grahic+|mediaobject+|mml:math))">
<!ENTITY % mathml PUBLIC "-//W3C//DTD MathML 2.0//EN"
        "http://www.w3.org/TR/MathML2/dtd/mathml2.dtd">
        %mathml;
        [..]
        <equation>
            <xi:include href="eqn/rgyr.xml" xmlns:xi="http://www.w3.org/2001/XInclude" />
        </equation>
        [..]


And eqn/rgyr.xml would go

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE mml:math PUBLIC "-//W3C//DTD MathML 2.0//EN" 
        "http://www.w3.org/TR/MathML2/dtd/mathml2.dtd" [ 
        <!ENTITY % MATHML.prefixed "INCLUDE"> 
        <!ENTITY % MATHML.prefix "mml"> 
        ]> 
        <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="rgyr">
        <mml:msub>
        [..]


Thanks for any hints,
