there's also a (make-standard-ucw-www-root-list) similar to the dispatchers

it's enough to (render (body zozo)). the semantics of the
switching-container is to render only the current component.


  (<:div :id "side-nav"
>          (flet ((zozo-link (name text)
>                            (<ucw:a :action (switch-component (body
> zozo)  name) ;; SNAG



the :action parameter was renamed to :action-body, because actions are
first-class citizens in _ajax and there's no way to distinguish between
forms that are meant to be executed as an action or to be called as forms
that return an action object (action-entry struct).

so either :action (register-ajax-action ...) or :action-body (do my stuff).
see the examples for details.


                                   (<:as-html text))))
>            (<:ul
>              (<:li (zozo-link 'zozo-zaza "Zaza"))
>              (<:li (zozo-link 'zozo-zuzu "Zuzu"))))))

i've started working on a tex file that collects the api differences between
the two branches. i'll commit it Real Soon Now...
