Yeah, just override #rendererClass like RSRSS does.

Just subclass WAActionPhaseContinuation and change #shouldRedirect to
answer false. You probably also need a custom
WARenderPhaseContinuation that does not create an HtmlRoot

The trickiest part is probably the action URLs and callbacks. You can
certainly make it work but it might require some ugly copy/paste code.
I might have time to hack something xml-based together.
