What is the XML rule for Placement for Groups?

<rule>    <description>Placement for Groups</description>    <conditions>        <and>            <if-class-name mode="nocase" op="equal">Group</if-class-name>          </and>      </conditions>    <actions>        <do-set-op-dest-dn>            <arg-dn>                <token-global-variable name="idv.dit.data.groups"/>                <token-text xml:space="preserve">\</token-text>                <token-src-dn/>              </arg-dn>          </do-set-op-dest-dn>      </actions>  </rule>
