UPDMRTF — unify representation style for inheritance

In case of UML, inheritance is described as “Generalization” in texts. However, in this document, inheritance is described as “Specializations”. It is confusing.

Unify the representation style for the inheritance, that is, decide which representation is taken.

Although the relationship is called generalization in UML, the term is dependent upon the direction from which the relationship is being viewed. If taken from the perspective of the element which is the is focus of a specific diagram (which is the case in this specification), the term used is specialization.
