	 * This class has two intrinsic properties:
	 * <ul>
	 * <li><strong>name </strong>-- The element name. The property value must
	 * be null or a String.
	 * <li><strong>extends </strong>-- The element that this element extends.
	 * Must be a String (for an unresolved name), DesignElement (for a resolved
	 * name) or null. The caller should ensure canExtend of this element is
	 * true.
	 * </ul>
	 * 
	 * @param propName
	 *            The name of the intrinsic property.
