Knowledge encapulation calls for, for almost any level of Secure reuse, a level of hiding. That may be to convey we have to defer the declaration of some data to a upcoming issue to ensure any client simply cannot depend on the structure of the info and will allow the service provider a chance to alter that composition if the need arises.
