Type - Type (internal data type)
A type is an item, which includes object types as specialization. Types are referenced by properties in order to define the way, property instances are represented. Types are also referenced (as object types) by classifications and categories.
Types do not support special features or feature relations. Those are defined for specialized types as object type and classification.
As an item, the type supports defining behavior and reactions of the general object as rules, events and causalities. These are typical features for object types, but also elementary types and classifications may define specific behavior.
