I don't put MathML directly beneath <informalequation>, so I can't say
for sure. However, I think the DocBook stylesheets may not be placing
<fo:instream-foreign-object> tags around your MathML.
If that is the case, you could fix it by including something like the
following (untested) template in your customization layer:
<xsl:template match="equation|informalequation|inlineequation">
<xsl:choose>
<xsl:when xmlns:mml="http://www.w3.org/1998/Math/MathML" test="mml:*">
<fo:instream-foreign-object>
<xsl:apply-templates/>
</fo:instream-foreign-object>
</xsl:when>
<xsl:otherwise>
<xsl:apply-imports/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
That still probably won't fix the problems with FOP not rendering your
MathML because, AFAIK, FOP doesn't handle MathML natively.
One option I am experimenting with (and will use if I can't make EPS
exports work the way I want them) is MathML->SVG conversion using
SVGMath[1].
Beware the default configuration file in SVGMath. It references the
Mathematica 7 True Type font from the MIT MathML fonts package for
FireFox. That font is not unicode compatable and will crash SVGMath.
The author, Nikolai Grigoriev, has modified his font file to be
Unicode compatible, so that is how it slipped into the config file. He
provided me with an alternate config file that doesn't use
Mathematica7 (but that also can't draw most double struck characters).
If he says it's okay, I could send it to you.
