TimelineMetadata uses the TimelineMarker class to represent both keys and values (i.e. a TimelineMarker will be stored as both key and value). A TimelineMetadata object dispatches a TimelineMetadataEvent when the currentTime property of the MediaElement's TimeTrait matches any of the time values in its collection of TimelineMarker objects.
