Where's the schema (DTD/XML Schema/Relax NG)?
Answer: there is no schema. Validating documents seems to have gone out of fashion. Writing a parser for HTML5 is extremely difficult. Basically the broken parsing behavior of old browsers is now standardized in a crazy arcane description of how to parse HTML5 documents.

Who benefits from such crazy parsing rules? The current browsers. This raises the bar for entry.
