hello Dan,

Thanks for the feedback on this draft tip (it is a draft, isn't it... 
checking, yes.)

As far as I know, the last generation of browsers have two modes, the 
"this document is valid I will behave nicely" mode, and the "damn, no 
doctype, I'll see what I can do" mode (aka quirk mode). Not that they 
differ wildly, but if developers keep following this trend, the 
difference may become sensible.

How is this relevant to the QA tip about doctypes?
XHTML1.0 second edition, section 3.1.1, point 4, and HTML 4.01 section 
7.2 both say "Use a doctype". If you want to change this, fine by me, 
but this is for www-html, not here.

This is a good one, and I will add it.

Thank you.
