Entity is an abstraction. It is designed to use various data
Each entity has @strong{representation-type}. It must be specified when
an entity is created. (cf. @ref{Entity Creation}) @refill

+Functions about entity are implemented by request processing to the
+entity. Each entity knows its representation-type. Each entity calls
+processing function corresponding with the representation-type. Such
