Titles provide tooltips. 
Should the potential tooltip be a factor in deciding whether to use title or desc?  
Obscured objects won't show a tooltip even if they have a title. Should that play a role in choosing title and desc?
What if the author does not want a tooltip on the object? Is using a desc OK?
Would having an aria-labeledby influence whether you use a title or desc?

 

 

U          p to a point. If there was no title, I think the accessible name computation would let you use aria-labelledby to make the desc element the accessible name for the parent svg. What if both an accessible name (title) and accessible description (desc) were needed though?

 

What was the reasoning behind the tooltip behaviour in the first place? I know it’s been there s
ince the year dot, but perhaps it’s the thing we need to look at – instead of playing with the accessibility layer?
