Hmm, although I basically understand what you're getting at, I'm a little
confused as to why I can't just do the following:

      <xsl:for-each select="(//dataset/*/*[generate-id() =
generate-id(key('dataids', concat(local-name(..),@dataId)))])">
         <xsl:sort select="//dataset/*/*[local-name() =
$sortColumn]/value"/>

and just sort the results of the grouping on the value of the child elements
value node?  It doesn't work, so I'm obviously missing something...
