  <tt:root name="ROOT"/>
  <tt:template>
    <node>
      <tt:value ref="ROOT"/>
    </node>
  </tt:template>
</tt:transform>

• DEMO_ST_XSDANY_LAX

<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
  <tt:root name="ROOT"/>
  <tt:template>
    <node tt:lax="on">
      <tt:value ref="ROOT"/>
    </node>
  </tt:template>
</tt:transform>
