We’re also fully intending to do something that none of the aforementioned specs really did, which is to have a comprehensive test suite that we will require at least two browsers to completely pass before we call it a day.
If one were to try to write such a test suite for HTML4 and DOM2 HTML, one would find that there isn’t even one browser that fully implements those specifications, let alone two.
The problem is that if we ever specify something that the browser vendors disagree with, they will just ignore the specification, and we might as well go home. If we write a specification that is ignored, we’re just fiction writers.
