Many of these things don't have exact definition in actual laws, either. I assume that a more detailed description will be made available as those policies are put into effect. Law systems generally rely on individuals designated to exercise judgment on a case-by-case basis, and, I assume, this will be the case here, too.

And even with actual law, people who may be satisfied with a particular law, may be very dissatisfied with a particular judge's interpretation and subsequent ruling, but that's how jurisdiction works.
