 *
 * <!-- begin-model-doc -->
 * An instance of a class can occur in a number of contexts. Each context has a characteristic condition that an object has to fulfill in order to "be in that context."
 * 
 * A context can specify constraints, additional events that the object may raise, or preconditions for operations of the object's class.
 * 
 * (Currently, the metamodel only describes context-based constraints; events and preconditions may have to be added later.)
