Containment Example
This examnple shows how to configure a concept Car to contain a concept Wheel by adding a ContainedConcept property Wheels, whose value is an instance of the concept Wheel.
The Wheels property provides the link between the container and contained concept:
Car (Concept) — Wheels (property) — Wheel (Concept)
The concept Car contains four instances of the contained concept Wheel, so you define the property as an array. The concept Car could also contain other concepts, such as Door and Engine, defined in a similar way using ContainedConcept properties.
However, the contained concepts — Wheel, Door, and Engine — cannot be contained by any other concept type. They can only be contained by the Car concept. For example, the concept Wheel cannot be contained in the concept Motorbike, if it is already contained by the concept Car.
Depending on your needs, another option would be to use a reference relationship instead of a containment or inheritance relationship.
