Changing font size for a chunk of text inline

Is there any way to change the font size for a short piece of text?

I have tried using the <phrase> and <emphasis> tags with various
attempts at customization.  The most likely thing I thought would work
was, taking a cue from Dean Nelson's font xsl file:

<!-- a desperate hack-->
<!-- Change the font size of the emphasis (and force non-italic) -->
<xsl:template match="emphasis[@font-size]">
    <fo:inline font-size="{@font-size}" font-weight="normal"
font-style="normal">
        <xsl:apply-templates/>
    </fo:inline>
</xsl:template>

But nothing changes.

My next step is to start modding the fo file, but that won't help the
html output any.

Ideas, anyone?

Thanks,
