Mathml font in phrase element with role=math attribute

["staffan molin" <sa.molin@gmail.com>]

Hello
How do i get the mathml font for the text within a <phrase
role="math"> element, in an xhtml output.
Now I use the following in my customization layer.
<xsl:template match="phrase[@role = 'math']">
        <xsl:call-template name="inline.italicseq"/>
    </xsl:template>
This will set the text to italic, it would be really nice if i can set
the correct font as well
