  Dear list contributors,

   in a recent post (http://lists.w3.org/Archives/Public/www-forms/2008Apr/0004.html)
   the request was mentioned to apply standard form control notification events upon
   initialization of form controls. Could you please clarify shortly -

    - will this request become an official requirement for future XForms specs ?

    - is there currently a way to force the validity notification on initial data
     (that is not covered by the definition: "an instance data node either changing and
     being or becoming invalid") ?

    - why is the notion of "validity" of a instance node bound to its UI control
      and not to the respective node, instance or a bind element referring to it ?

   Examples: A (required) node is initialized to an invalid value,
   no "xforms-invalid" event is triggered preventing any implicit or
   explicit error recovery or UI adjustment. In contrast the CSS
   pseudo-classes (:valid, :invalid) are effective and allow
   to mark the invalid control.

   Also one would prefer to handle the invalidity of "hidden"
   (calculated) values by the generic means of event handling,
   like registering a handler on the instance or a bind element.

   Many thanks
    Jaro Pullmann
