Then you should be able to easily nest two for-each-group group-by

  <xsl:template match="Set">
    <xsl:for-each-group select="Stamp" group-by="Formats/@se-tenant">
      <xsl:for-each-group select="current-group()" 
select="string-join(Value/@*, '|'">
        <!-- now the first Stamp in each group is simply . e.g. -->
        <xsl:value-of select="./Value/@*/concat(local-name(), '=', .)" 
separator=" "/>
         <br/>
      </xsl:for-each-group>
    </xsl:for-each-group>
  </xsl:template>
