irrelevant="", <audio> and <source> have been added. <video> might have  
gotten some new attributes too.

irrelevant="" is a boolean and indicates that the element is not relevant.  
It addresses use cases where today style="display:none" is probably used  
instead.

<audio> is the counterpart of <video>.

<source> is a way to provide alternative formats for <audio> or <video>,  
where the UA chooses the best one.
