65 No functional terminology list without rules

As said before, it is impossible to draft a functional list of terminology without a set of model rules behind it, and vice versa. That in turn makes it desirable to consider a rather wide coverage of the CFR. For example, it would be very difficult to develop a list of key notions of the law on contract and contractual obligations (such as ‘conduct’, ‘creditor’, damage, ‘indemnify’, ‘loss’, ‘negligence’, ‘property’ etc.), without a sufficient awareness of the fact that many of these notions also play a role in the area of non-contractual obligations.
