Oops, forgot a few details:

  </xsl:stylesheet>

On second thought, if the descending scope-elements *always* appear after
their parent, this will be better performance-wise (starting right before
creating the scopes-element in the second template above):

      <xsl:if test="following::scope[@parent_id=$vId]">
        <scopes>
          <xsl:apply-templates select="following::scope[@parent_id=$vId]" />
        </scopes>
      </xsl:if>


Cheers,

Andreas
