Your first point is not relevant to my post, I am referring to the point whether the vote counts or not and arguing from the legal perspective you can easily argue that it does not.
However of course you can have a legally binding referendum without lots of specifics. All it requires is that the act states it's legal binding .i.e."A UK referendum will only have the force of law if the Act setting it up says so." Nothing says it has to have a load of specifics. I only mentioned 2, who says you have to have resolved all the questions?
