This ReferenceType can be used to expose the relation between a component to other components, that the component requires in order to work. In contrast to the HasComponent ReferenceType, the related components are not considered to be subcomponents of the component. In contrast to the Utilizes ReferenceType, this hierarchical ReferenceType exposes a non-looping hierarchy of dependencies.
For example, it can be used to relate an axis of a motion device to its required powertrains or a software component to other software components required to execute the software component, like for example libraries.
