I see your point - video is clearly more popular then RDFa and if you're
willing to go off-standard to support it, it's might be a reasonable
decision for a site like Wikipedia. Not sure what is the rush for that and
why can't it wait till HTML 5 spec becomes a recommendation.

I'm not that familiar with HTML 5 support in modern browsers to state that
there are going to be regressions with some other things, but it might be
another thing to consider, although Wikipedia might be big enough to be a
driving force in such decisions.

Sorry, can't give you a definitive answer - CCing RDFa list for this.

Guys, will be happy if you provide where RDFa support stands here.
