  /**
   * This handler is used for the navigation nodes that request content from an external URL. This
   * handler pulls the "real url" from from the component specified by the <code>compId</code>
   * parameter (this necessarily depends on the presence of the navigation container in the view for
   * the component look up to work). Once the component has been found, the url is retrieved from
   * the attribute map, and its contents retrieved. If <code>processPage</code> is true, the URL
   * contents are interpretted and the resulting component(s) are added to the component tree (This
   * feature is not currently supported).. Otherwise, the contents are returned in the output
   * parameter <code>pluginPage</code> to be output as-is on the page.
   *
   * @param handlerCtx The <code>HandlerContext</code>.
