[WebTiming] HTMLElement timing

Folks,

     Thanks to the much feedback from various developers, the WebTiming
specs has undergone some
major revision. Timing info has now been extended to page elements and a
couple more interesting timing
data points are added. The draft is up on
http://dev.w3.org/2006/webapi/WebTiming/

     Feedback and comments are highly appreciated.

cheers,
Zhiheng
