I think that a function that would not rely on regexp could improve
drastically the performance.
For seconds are needed to load the html5-spec page. And most of the time is
spent identifying tags. So any micro optimization can have a huge impact.

(I have previously won 20% in perfomance when I modified the tag attributes
parser function to use chars instead of strings. I would have never thought
that the gain would be so large)
