My understanding of TA's is the prescription level is a statement about 
the predicate in cases where the prerequisite is true.

If the prerequisite is false, then the test is skipped.

So a mandatory requirement would have a null prerequisite, or some other 
notation saying that that TA always applies as well as a "mandatory" 
prescription level.  But an optional requirement would have a non-null 
prerequisite and/or a non-mandatory prescription level.
