 * A representation of the model object '<em><b>General Ordering</b></em>'.
 * <!-- end-user-doc -->
 *
 * <!-- begin-model-doc -->
 * A GeneralOrdering represents a binary relation between two Eventoccurrences, to describe that one Eventoccurrence must occur before the other in a valid trace. This mechanism provides the ability to define partial orders of EventOccurrences that may otherwise not have a specified order. A GeneralOrdering is a specialization of NamedElement. A GeneralOrdering may appear anywhere in an Interaction, but only between Eventoccurrences.
