 * However, all content elements have at most one container. And, all elements
 * (except the root) have a container. So, the content-to-container relationship
 * is modelled in this element base class.
 * <p>
 * Containers have one or more <em>slots </em>. See the
 * {@link org.eclipse.birt.report.model.metadata.SlotDefn}class for a detailed
 * description of slots.
 * <p>
 * Members in the containment system include:
 * <p>
 * <ul>
 * <li>The {@link #container}member that caches a pointer to the container
 * element.</li>
 * <li>The {@link #getContainer}method to get the container element.</li>
 * <li>The {@link #setContainer}method to set the container element.</li>
 * <li>The {@link #getSlot}method returns a slot within a container.
 * <li>The {@link ContainerSlot},{@link SingleElementSlot}and
 * {@link MultiElementSlot}classes that represent slots.</li>

 * The notification system allows any number of {@link Listener}objects to
