As a list is used, a user may decide to apply a level-1, level-2 and
level-all parameter at the same time. An implementation SHOULD
prefer a level specific parameter over level-all parameter. As
example, if priority is 100 for level-1, 200 for level-2 and 250 for
level-all, the implementation should use 100 for level-1 and 200 for
level-2.
