Ah, I see I forgot an important detail (sorry, guys)
There are only 4 different such CreditCardCompanies (in my system,
currently), and I want to use them only as components of the
Purchase.CreditCard class.
So Purchase is an persisted entity, it has a component CreditCard. The
Credit card has one of the 4 predefined CreditCardCompany
implementations as a property 'Company', similar to an enum.
Actually it has been an enum in the past (persisted with
EnumStringType), but now I want to inject card specific behavior into
it, that's why I converted it to classes.
