I confirmed that I was set definitely without becoming xml if you made the modifications that you taught.

* When I set true with cib.xml file.(sequential=true)
(snip)
    <constraints>
        <rsc_order id="test-order">
                <resource_set sequential="true" id="test-order-resource_set">
                        <resource_ref id="Dummy01"/>
                        <resource_ref id="Dummy02"/>
                </resource_set>
        </rsc_order>
    </constraints>
(snip)

[root at rh64-heartbeat1 ~]# crm 
crm(live)# configure
crm(live)configure# show
(snip)
group testGroup01 Dummy01 Dummy02
order test-order : _rsc_set_ Dummy01 Dummy02
(snip)

Many Thanks!
