The parent group merge algorithm enables the system to merge policies that contain
references to parent groups and create an internal parent group for each internal parent
group in a component policy in the final merged policy. There is a one-to-one
correspondence between an internal parent group in the merged policy and an internal
parent group in a component policy.
