For the time being its going to be more of a "I'll know it when I see it and so will you" type of situation. Preventing scams and things advertised as investment opportunities appear to be the focus without trying to pin down an exact framework for detecting it, but I wouldn't say they are being vague about what it is they're are going to limit. If they tried creating an exact framework with the information available today it would likely miss the mark in terms of a balance between restrictiveness and protection to investors/purchasers.
