"On further reflection, I've come to the conclusion that it's better not to try to think about repeating groups at all in this context, but rather to focus on (and then, as I've just done, to debunk!) the notion of atomicity instead.

Date, Database Design and Relational Theory: Normal Forms and All that Jazz, 2nd Ed, 71-72.
