Composition
The composition relationship indicates that an element consists of one or more other elements.

The composition relationship has been inspired by the composition relationship in UML class diagrams. In contrast to the aggregation relationship, the composed concept can be part of only one composition.

A composition relationship is always allowed between two instances of the same element.

In addition to this, the metamodel explicitly defines other source and target elements that may be connected by a composition relationship.
