There would be lots of different specific points throughout the legislation that would refer to level 2 and how it was different from levels 3 and 4. It's not just inventory; it's authorization of folks coming into labs and maintaining lists of people who come in and out of labs. Pretty well throughout all of it you could have a question that would pertain to level 2, so you'd have to make exceptions throughout the course of the legislation. They could be minor points, but the breadth would be significant.
