Hi Richard,

Right, but that's the true regardless of whether SVG2 allows the 
attributes or not.

As far as I can tell, it will only make a difference if the author looks 
at the spec, sees that role is permitted on <desc> and then assumes some 
mapping. Or, alternatively, if they use a validator tool that might 
otherwise have alerted them that 'role' is not permitted on <desc>.

I think both are unlikely and easy to workaround if necessary.

It probably doesn't matter a whole lot but unless there's a strong 
reason not to, allowing the attributes everywhere seems to me to be 
simpler, shorter and more consistent.

Yes, I was hoping you could make those changes along with your other 
aria-related edits.

Thanks!

Best regards,

Brian
