 * A model proxy factory creates model proxies for elements based on

 * This interface is an alternative to the {@link IModelProxyFactory} 
 * interface. Unlike its predecessor <code>IModelProxyFactory2</code> allows 
 * the full path to the tree element to be specified when creating an 
 * <code>IModelProxy<code> instance.  Using the full patch allows models to 
 * provide proper model deltas even if the root element of this proxy is at 
 * variable or unknown location in the viewer.
 * </p>

 * Clients may implement this interface.
