RE: XSLT 2.0 Multi-level grouping

Looks to me like

<xsl:template match="Computers">
  <xsl:for-each-group select="*" group-by="name()">
    <xsl:element name="{current-grouping-key()}">
      <xsl:for-each-group select="current-group()/*" group-by="name()">
        <xsl:element name="{current-grouping-key()}">
          <xsl:copy-of select="current-group()"/>
