Aligning figure headers in FO/PDF

["Derek Hohls" <DHohls@csir.co.za>]

I would like to get the figures and the figure captions aligned
in the FO/PDF output.  I have tried:

<xsl:attribute-set name="figure.properties" 
                   use-attribute-sets="formal.object.properties">
   <xsl:attribute name="text-align">center</xsl:attribute>
</xsl:attribute-set>

in my customization file; this works fine for the figure, which
is now centered, but the caption is still left-aligned.  Is there
another parameter, or attribute set I should be customizing?

Thanks
Derek
