HTML5 being developed by WHATWG according to an Apple dev docs page

from http://developer.apple.com/documentation/iPhone/Conceptual/SafariJSDatabaseGuide/Introduction/Introduction.html

"HTML 5 is currently in development by the Web Hypertext Application
Technology Working Group (WHATWG)."

The link to the SQL section of HTML5 on whatwg site at the bottom of
the page is broken

Cheers,
Dave
