Encouraged by Håkon and Michael(tm) I took my talk on HTML5 near the end of the lightning talk session at XTech 2007 and ripped out all the boring stuff and gave a five minute presentation: Evolving the Web: HTML5 (XTech edition). The actual idea was doing twenty slides of which each takes twenty seconds. I think I had more slides, but probably sticked within the time limit. Preparing it was all kind of adhoc, but doing something like this is highly recommended.
By the way, I think the latest e-mail from Ian Hickson on complex tables and the one from Maciej clearly shows that we are very much interested in accessibility. I think the WHATWG has developed a different kind of approach to these kind of issues over the years from other people, which may led people to think we don’t give a shit about it or something.
For informtation, your XHTML5 file doesn't validate. :p See here for more details... Apparently, putting lang="en" in the top html tag is forbidden. But very interesting talk, by the way. :)
I expect that the specification and conformance checker will be updated in due course.
Or maybe you should have used xml:lang instead (since you're doing XHTML)... (see The lang (HTML only) and xml:lang (XML only) attributes)
Yes, I know what the specification currently suggests.
So you don't agree with the current specification which you expect to change... Why? Do you think it's a bad idea to keep lang for HTML & xml:lang for XML?
