Class Precedence List: DurationObservation, Observation, PackageableElement, ParameterableElement, NamedElement, Element

Properties:

event : NamedElement (1 2); -- source DurationObservation
firstEvent : Boolean (0 2); -- source DurationObservation
visibility : VisibilityKind (1 1); -- source PackageableElement
owningTemplateParameter : TemplateParameter (0 1); -- source ParameterableElement
templateParameter : TemplateParameter (0 1); -- source ParameterableElement
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

A name which allows the NamedElement to be identified within a hierarchy of nested Namespaces. It is constructed from the names of the containing namespaces starting at the root of the hierarchy and ending with the name of the NamedElement itself.

ownedComment : Comment (0 *); -- source Element
ownedElement : Element (0 *); -- source Element
owner : Element (0 1); -- source Element

The OCL used here is not normative.
Editor's notes: Added endif.
Expression: if (event->size() = 2) then (firstEvent->size() = 2) else (firstEvent->size() = 0) endif
