It would be great if W3C had a specification for script elements as XML 
Events handlers.
(Still waiting to see the "companion specification", 
http://www.w3.org/TR/xml-events/Overview.html#section-eventhandlers)

Do Opera and NetFront handle <script> in the same way? For example, is 
the event object accessible from the script (probably using |event| ) 
and what is the |this| object in the script? How, or based on what is 
the script execution deferred when the element is a handler (i.e. where 
did the "declare" attribute come ;) that is not HTML4. XHTML2 Object 
module has that attribute...)?
