To be frank Sylvia, in my experience, the previous editor of the HTML5 
spec was rather ambivalent/ambiguous about where and when the spec 
would/should define the user experience. There are parts of the spec 
where this is defined in a granular way, and then other parts where Ian 
would openly say "We should not define the user experience".

Note, this was usually when talking about a11y, and when he may not have 
fully understood the implications of that mantra. So do you think that 
the HTML5 spec should clearly define the user experience of its a11y 
related elements?

Would it help you if we did try to define it more clearly?

It would be great if so, as it makes this whole conversation more practical.
