AMC and GM are not included: they show ways to comply; this list is what the rule itself requires. Section B, what the competent authority does, is not included.
A summary can lose a nuance. The rule text binds, together with your approved exposition and your competent authority. Not the official publication — verify against the Official Journal of the European Union before operational use.
