CopsRoleCombination
A display string consisting of a set of roles concatenated with '+' characters where the roles are in lexicographic order from minimum to maximum. Policies are assigned to a 'role', and one or more 'roles' are assigned to interfaces, such that an interface takes on the policies indirectly as the policies of the roles assigned to that interface. When one or more roles assigned to an interface, that set of roles is known as a role-combination.
