	 * <LI>Provide methods for setting and getting the data object.</LI>
	 * </UL>
	 * <P>
	 * Additionally, <code>IProxy</code>s typically:</P>
	 * <UL>
	 * <LI>Maintain references to one or more pieces of model data.</LI>
	 * <LI>Provide methods for manipulating that data.</LI>
	 * <LI>Generate <code>INotifications</code> when their model data changes.</LI>
	 * <LI>Expose their name as a <code>public static const</code> called <code>NAME</code>, if they are not instantiated multiple times.</LI>
	 * <LI>Encapsulate interaction with local or remote services used to fetch and persist model data.</LI>
