	 * identified by a container ID. The application creates the element object,
	 * then adds it to the container here. The undo of this operation
	 * effectively deletes the element.

	 * @param content
	 *            the element to add
	 * @param slotID
	 *            the slot in which to add the component
	 * @param newPos
	 *            the position index at which the content to be inserted. If
	 *            it's -1, the content will be inserted at the end of the slot.
	 * @throws ContentException
	 *             if the content cannot be added into this container.
	 * @throws NameException
	 *             if the name of the content exists in name space.
