Is it the case that groups propagate "up" whereas roles propagate "down" for
security purposes?
For example:
humans is a subgroup primates
X is a member of humans
----------------
X is a member of primates = True
humans is a subgroup primates
X is a member of primates
-----------------
X is a member of humans = Unknown
junior auditor is a child-role of senior auditor
X can play role junior auditor
-----------------
X can play role senior auditor = Unknown
junior auditor is a child-role of senior auditor
X can play role senior auditor
-----------------
X can play role junior auditor = True
