I'm happy with most of this, except for:

Depending on ordering, this advice either doesn't work for Firefox 
(including FF4), or for IE8 (and below). See 
<http://greenbytes.de/tech/tc2231/#attfnboth> and 

That's why I ended up with the statement abour U-A sniffing. Nobody 
likes it. I don't like it. But like it or not, it's what you need to do 
as of today.

The alternative of course is not to have any advice here, and just link 
to something we can update more quickly.

Best regards, Julian
