NOTE: The naive parent group merging algorithm is not compatible with this
parent group merge algorithm. If you have service definitions that used the
naive parent group algorithm, you need to modify those service definitions
to work with this algorithm.
If there is no existing internal parent group with the same name in the merged policy,
the system creates a corresponding internal parent group with the same name.
If an internal parent group with the same name already exists, the system uses a name
built by appending an internally generated sequence number to the name of the internal
parent group in the component policy.
If the length of the name exceeds the maximum length allowed, the policy merge fails.
If a classifier group in a component policy refers to an internal parent group, the same
classifier group in the merged policy corresponds to the internal parent group in the
merged policy.
If a classifier group in a component policy refers to an external parent group, the same
classifier group in the merged policy refers to the same external parent group.
If there is a conflict where two or more component policies contain the same classifier
group referring to an internal parent group in a corresponding component policy or to
an external parent group, then last one is used.
In the following example, component policies P1 and P2 create the merged policy
mpl_88000001.
