Common exceptions to this rule include detection spells (such as Arcane Sight, Detect Aberration and Detect Good/Evil/Chaos/Law, to self only), minor enhancement bonuses to existing qualities of the character (such as Magic Fang to existing natural attacks, and Resistance to existing saves) and size bonuses (Enlarge/Reduce Person).
The bolded portion is a little unclear: are those examples of acceptable bonuses, or unacceptable? I would have assumed the former except that the other examples are all fairly clearly unacceptable. A bit of rewording might be good just in case.
