Note that the fact that HTML5 is in last call NOW make it quiet unlikely  
that any extension will be ready in time to go into this version of the  
if we are talking about a major addition that still need to be discussed,  
defined, presented to the HTML Wg etc.

This doesn't mean that this cannot be discussed and worked on by this  
group first and by a WG later on and included in the next version of HTML  
(6?) when is mature
I think the HTML groups is also collecting a list of "new features" for  
next releases, so our input could be provided to them.

Kaz and Francois (CCed) should be able to confirm/clarify a bit what I  
just said about the W3C procedures and deadlines and maybe even give us  
more details.
