That's a good question.

FF, IE9, Webkit: Enforces a single doctype and a single element.
Opera: Enforces a single element, but allows multiple doctypes.

So it seems the one element, one doctype rule is already pretty well
enforced.

I'd like to change the spec so that instead of requiring a specific
ordering, it requires that the serialization of the document (for example
through XMLSerializer) always reflects the current document state, even if
you removed the doctype node entirely. That ensures that serializing a live
document gets you something that would render the same a second time.
