Interesting. I'm quite surprised that many people coming from WHATWG
camp are somewhat flexible with arguments.

Once support for legacy stuff is treated as something to which HTML5
must fits completely (e.g. <!DOCTYPE html>, <meta charset="...">). Other
time, 8 years old technology which is widely deployed (XSLT 1.0) is
accused of not supporting HTML5.

In ideal world -- of course. In real world -- hardly. Who will pay for
doing necessary changes?

With this approach I could say that there is no good reason why XHTML
parsing mode could not be added to the Web browsers. Sounds silly, isn't?

I think that HTML5 should be as backwards compatible as possible. I
think that all will agree with this.

The question is what do will less harm (I'm talking only about HTML
serialization):

1. Requiring <!DOCTYPE html>

2. Allowing <!DOCTYPE html>

3. Requiring either <!DOCTYPE html> or <!DOCTYPE html PUBLIC "...">

And please bear in mind that there are other tools then notepad and
browsers which deal with markup.
