I agree with Professor Staines that it would be almost impossible, never mind practical, to have definitions that would have to be enforced by police or port authorities. My question was more about having an advisory mechanism, because with clearer definitions, people might better understand what was deemed to be essential and non-essential, as opposed to making judgments that in the end may be wrong.
