Jeni's grouping example helped me solve a similar problem
(http://www.jenitennison.com/xslt/grouping/muenchian.html).

<xsl:template match="some-element">
   <xsl:for-each select="hdl[count(.|key('uq', @id)[1]) = 1]">
      <mod><xsl:value-of select="@id"/></mod>
         <xsl:for-each select="key('uq', @id)"/>
   </xsl:for-each>
</xsl:template>

I want to remove duplicate nodes by looking at an attribute (in this case
id).  Can anyone suggest a good way to do this.
