Fair enough...I'll cop to not knowing much about HTML5, my knowledge stopped with HTML4. I went and referenced the parsing rules and they are quite the mess. There's no official grammar for HTML5 that I can find and even if there was, I don't think there's a solid parser generator out there that handles anything more powerful than context-free grammars.
