/**
 * A dependency states that the implementation or functioning of one or more
 * elements requires the presence of one or more other elements.
 *
 *
 *
 * In the metamodel, a Dependency is a directed relationship from a client (or
 * clients) to a supplier (or suppliers) stating that the client is dependent on
 * the supplier (i.e., the client element requires the presence and knowledge of
 * the supplier element).
 *
 *
 *
 * A dependency specifies that the semantics of a set of model elements requires
 * the presence of another set of model elements. This implies that if the source
 * is somehow modified, the dependents probably must be modified. The reason for
 * the dependency can be specified in several different ways (e.g., using natural
 * language or an algorithm) but is often implicit.
 *
 *
 *
 * Whenever the supplier element of a dependency changes, the client element is
 * potentially invalidated. After such invalidation, a check should be performed
 * followed by possible changes to the derived client element. Such a check should
 * be performed after which action can be taken to change the derived element to
 * validate it again.
