how to number on a grouped and sorted set?

[Chad Small <chad.small@xxxxxxxxxxxxxxxxxx>]

I'm working with a group and sort set defined like this and just want to
write the order (number - 1,2,3,etc.) into the last element called <rank>.
How do I do that?

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
  <xsl:key name="g" match="result" use="cuicode"/>
  <xsl:output indent="yes"/>
  <xsl:template match="/">
    <ConceptResults>
    <xsl:for-each
select="ConceptResults/result[generate-id(.)=generate-id(key('g',cuicode)[1]
)]">
      <xsl:sort data-type="number" select="sum(key('g',cuicode)/bitmask)"
order="descending"/>
      <xsl:sort data-type="number" select="key('g',cuicode)/count"
order="descending"/>
      <xsl:sort data-type="number" select="key('g',cuicode)/offset"
order="descending"/>
      <xsl:variable name="results-with-same-cuicode"
select="key('g',cuicode)"/>
      <result>
        <url><xsl:value-of select="url"/></url>
        <offset><xsl:value-of select="offset"/></offset>
        <phrase><xsl:value-of select="phrase"/></phrase>
        <bitmask><xsl:value-of
select="sum($results-with-same-cuicode/bitmask)"/></bitmask>
        <cui><xsl:value-of select="cui"/></cui>
        <count><xsl:value-of select="count(key('g',cuicode))"/></count>
        <cuicode><xsl:value-of select="cuicode"/></cuicode>
        <cuidscr><xsl:value-of select="cuidscr"/></cuidscr>
        <rank><xsl:number level="single" from="."/></rank>
<---------------------------------------- how do I get the grouped number
and not the original number
      </result>
    </xsl:for-each>
    </ConceptResults>
  </xsl:template>
</xsl:stylesheet>

thanks,
chad.
