The current stylesheets are not very sophisticated. The
MathML markup gets
through to the output, but that's about it.
The following customization adds support for  align and
valign on imagedata
(the original template is in math.xsl):
<xsl:template match="mml:math"
xmlns:mml="http://w
ww.w3.org/1998/Math/MathML">
<xsl:choose>
<!-- * If user is using passivetex, we don't wrap the
output in -->
<!-- * fo:instream-foreign-object (which passivetex
doesn't support).
-->
<xsl:when test="not($passivetex.extensions =
0)">
<xsl:copy>
<xsl:copy-of select="*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:when>
<xsl:otherwise>
<fo:instream-foreign-object>
<!-- Support for two imagedata attributes -->
<xsl:if test="../align">
<xsl:attribute name="text-align">
<xsl:value-of select="../align"/>
</xsl:attribute>
</xsl:if>
<xsl:if test="../valign">
<xsl:attribute name="display-align">
<xsl:choose>
<xsl:when test="../valign =
'top'">before</xsl:when>
<xsl:when test="../valign =
'middle'">center</xsl:when>
<xsl:when test="../valign =
'bottom'">after</xsl:when>
<xsl:otherwise>auto</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
</xsl:if>
<!-- End of customization -->
<xsl:copy>
<xsl:copy-of select="*"/>
<xsl:apply-templates/>
</xsl:copy>
</fo:instream-foreign-object>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
I'm not sure if this is the way to go in the long run. I
guess that it would
be better if the process.image template in graphics.xsl
could be reworked so
that it also supports imagedata attributes for MathML (and
SVG).
