Ein `AssemblyContext` instanziiert eine Komponente. Gäbe es demnach einen `AssemblyContext` des Systems, würde das doch bedeuten, dass das System an sich als Komponente betrachtet werden würde. Zudem frage ich mich dann, wo dieser `AssemblyContext` \"verwaltet\" wird. Im System selbst?\r\n\r\nMeinem Verständnis nach hat ein System lediglich Schnittstellen und kapselt die existierenden `AssemblyContexts`:\r\n> A system also encapsulates assembly contexts and provides at least one interface.\r\n\r\n(*Du beziehst dich schon auf das Metamodell und nicht auf die Modellierung des Beispiels, oder?*)"}}
