They provide all kinds of warnings about misinterpreting the data provided, which amounts to pretty firm implementation advice, and identifies ways you can shoot yourself in the foot. But none of those sections are normative. (Actually there are two SHOULDs in 7.4, but in retrospect they shouldn't really be there.)
