22  * an element.
23  * <p>
24  * This interface is an alternative to the {@link IModelProxyFactory}

26  * the full path to the tree element to be specified when creating an
27  * <code>IModelProxy<code> instance.  Using the full patch allows models to
28  * provide proper model deltas even if the root element of this proxy is at
29  * variable or unknown location in the viewer.
