This method will not add the markup automatically. Am I right?

I want to append incoming LiveFragments to the page.

Right now, I am doing something like this on the client:

// import Divmod.Runtime

What.Ever = Nevow.Athena.Widget.subclass('What.Ever');
What.Ever.methods =(

  function foo(self) {
    d = self.callRemote('getLiveFragment');

    d.addCallback(

      function liveFragmentReceived(lf) {

        d2 = self.addChildWidgetFromWidgetInfo(lf);

        d2.addCallback(

          function added(res) {

            d = Divmod.Runtime.theRuntime.parseXHTMLString(
              lf.markup).documentElement;

            self.nodeById('lastNode').appendChild(d);

          });

      });

  });

Is this the official way of doing that, or am I missing something?
