	DTOR.
virtual void	realize (const makArchives::DtMetadataPublisherRecord &metadataConfig)
	Initialize a publisher from a DtMetadataPublisherRecord.
virtual void	setObserverName (const DtUnicode &observerName)
	Set the name of the observer that this publisher will track.
virtual bool	isAttached ()
	Get whether the publisher is attached to an entity other than the observer.
virtual void	attachEntity (makVrv::DtUniqueID entity)
	Tell the publisher to attach to an entity.
virtual void	detach ()

virtual void	addMetadataElement (DtMetadataElement *element)
	Add a metadata element.
virtual int	numBytes ()

	Get the publisher's buffer of metadata.
virtual const DtVideoStream &	videoStream ()
	Get the video stream that the metadata is being added to.
virtual const DtSceneObject &	attachedEntitySceneObject ()
	Get the DtSceneObject that we are attached to, if attached to an entity rather than an observer (isAttached is true).
virtual const DtObserver &	observer ()
