Hi Andrew,
Thank you for comments.

Which next case does your answer correspond to?
Case 1) Cannot replace "ordered=false" of group with "sequential". Therefore, the "ordered" attribute of the group resource continues being supported from now on.
Case 2) It works in the same way if I exclude rsc_order id="test-order" like the next setting. (rsc_colocation sequential="false", remove rsc_order id="test-order".)
(snip)
<resources>
<group id="testGroup01">
<primitive class="ocf" type="Dummy" provider="heartbeat" id="vip-master">
<operations>
(snip)
<primitive class="ocf" type="Dummy" provider="heartbeat" id="vip-rep">
<operations>
</group>
(snip)
<constraints>
<rsc_colocation id="test-colocation">
<resource_set sequential="false" id="test-colocation-resource_set">
<resource_ref id="vip-master"/>
<resource_ref id="vip-rep"/>
</resource_set>
</rsc_colocation>
</constraints>
(snip)
Case 3) There is a method to set ordered="false" of group elsewhere.
Best Regards,
Hideo Yamauchi.
