 * The default widget for properties of type rdf:List (or a subclass of rdf:List).
 * It looks similar to a normal instance list widget but operates on a linked RDF list.
 * <p/>
 * It is possible to subclass this widget class to operate on simulated lists with first
 * and rest properties.  To do so, overload the corresponding methods of the RDFListComponent class.
