What kind of theoretical points are these? Do you want to teach me 
about HTML4 and SGML etc?

HTML5 sees only one purpose for a DOCTYPE: trigger or not to trigger 
certain parsing mode. And until now I believed that anything that 
triggered strict parsing up until now, would continue to do so.

Again a theoretical point.

The issue that I have taken up is that Minefield, Safari 4 and Opera 
10.5beta _they_ do use that DOCTYPE to do something bad.

You - these browsers - are in effect using the version info - the 
DOCTYPE - to change the parsing behaviour. It is not how Maciej 
believed - that HTML5 contains a definite list of those DOCTYPEs that 
trigger quirks mode.

This will kill off the extendibility of already published versions of 
HTML. Or make quirksmode popular.
