How could rel=help, which implies the help text would be structured  
text at another URI, be better than using a simple string from an  
attribute that Opera 9 already supports for this purpose at least  
visually? Would rel=help come with roughly similar cans of worms as  

If I enter an ftp URI in the address box on http://html5.validator.nu/  
in Opera 9 or 10 and hit enter, I get a visual popup that tells me the  
format of the input is wrong and then includes the value of the title  
attribute (per current spec).

Why wouldn't an HTML5 forms-aware browser expose that popup to AT the  
same way such a GUI popup would be exposed to AT in a non-browser app?  
Why should AT have to know which attribute the text came from?
