One of the things I like about the current serialization rules is that the engine can parse and then serialize something for an element that is not yet known to the engine and it behaves no differently than one that is know. Attributes are simply strings. Having a different rule for boolean attributes would change that. Not a major concern, but something that bothers me slightly. It’s one thing to be HTML-aware and another to be future-of-HTML-aware.
