Which HTML elements can receive focus?

Question

I\'m looking for a definitive list of HTML elements which are allowed to take focus, i.e. which elements will be put into focus when focus() is called on them?<

The ally.js accessibility library provides an unofficial, test-based list here:

(NB: Their page doesn't say how often tests were performed.)
