wxXmlResourceHandler is an abstract base class for resource handlers
capable of creating a control from an XML node.
+See \helpref{XML-based resource system overview}{xrcoverview} for details.
+
+{\bf NOTE:} XRC is not yet a part of the core wxWidgets library, so
+please see the overview for how to compile and link it. Otherwise if you
+try to use it, you will get link errors.
