finish : OccurrenceSpecification (1 1); -- source ExecutionSpecification
start : OccurrenceSpecification (1 1); -- source ExecutionSpecification
covered : Lifeline (0 *); -- source InteractionFragment
enclosingInteraction : Interaction (0 1); -- source InteractionFragment
enclosingOperand : InteractionOperand (0 1); -- source InteractionFragment
generalOrdering : GeneralOrdering (0 *); -- source InteractionFragment
clientDependency : Dependency (0 *); -- source NamedElement
name : String (0 1); -- source NamedElement
nameExpression : StringExpression (0 1); -- source NamedElement
namespace : Namespace (0 1); -- source NamedElement
qualifiedName : String (0 1); -- source NamedElement
