We don't fully implement the HTML5 parsing algorithm, but I believe  
that when we do, it will make our parsing code simpler rather than  
more complex. The HTML5 parsing algorithm makes a lot of things  
systematic that are messy ad-hoc cases in our current parsing code. As  
an example of this, we do have a pretty much HTML5-compatible  
tokenizer for our preload scanning, and it is a lot cleaner than the  
main tokenizer.

Part of my excitement about the HTML5 parsing algorithm, as a browser  
implementor, is that it will simplify our parsing code while also  
making it more compatible with content and more interoperable with  
other browsers. If I thought it would be a lot more complicated than  
our current code, I would probably be opposed to implementing it.
