Example 2a

We can now create and add "Child" price entities to the CFA. The first price entity we create is an ACME specific price for SMS usage (.05 per use):

The Tariff is for SMS usage (the Usage=Characteristic, and the CharacteristicsCharge Relationship specifies "SMS"). Also note that we have made this price object a child of the CFA_1 price object. Therefore, this Tariff will apply only to ACME worldwide, since it is part of ACME's CFA_1 price agreement.
