2.2.13.2. Inheritance
One object type can extend another object type by adding or replacing fields
and methods. In this case the new object is said to be a descendant object;
the older object is said to be an ancestor object. The process of an extension
is called its inheritance. The descendant object type may have its own
descendants; these are also viewed as the descendants of the original ancestor
object. The domain of an object, is the object together with all of its
descendants.
