[Pacemaker] [Question] About replacing in resource_set of the order limitation.

Hi All,

My test seemed to include a mistake.
It seems to be replaced by two limitation.

      <rsc_order id="rsc_order-clnPing-grpPg1" score="0" first="clnPing" then="prmEx" symmetrical="false">
      </rsc_order>
      <rsc_order id="rsc_order-clnPing-grpPg2" score="0" symmetrical="true">
        <resource_set id="rsc_order-clnPing-grpPg2-0" require-all="false">
          <resource_ref id="prmEx"/>
          <resource_ref id="prmFs1"/>
          <resource_ref id="prmFs2"/>
          <resource_ref id="prmFs3"/>
          <resource_ref id="prmIp"/>
          <resource_ref id="prmPg"/>
        </resource_set>
      </rsc_order>

If my understanding includes a mistake, please point it out.

Best Reagards,
Hideo Yamauchi.
