Abstraction is expressed in three permitted ways: behavior elements stand for logical, implementation independent components while the active structure elements assigned to them stand for physical components; realization links concrete elements to the abstract elements they fulfil, including requirement to principle links and component to component links; and logical or physical variants may be defined as specializations of a base element through the customization mechanism. Models describe types or exemplars rather than individual instances.
