Re: name and description calculation - is there a mismatch between the document and what Apple implements?

Joanie,

I don't need to know whether any SVG testable statements are out of sync
with what is implemented this week.

For the ARIA working group, it would be nice to know if the name
calculation in the accname mapping table sometimes doesn't match what Apple
does so whatever issues are in accname can be raised and addressed.  When
Amelia and I were talking about it in the SVG accessibility meeting, I
think I heard Rich groan...

We decided yesterday, that SVG elements with a title or desc and role
none/presentation - should be included in the accessibility tree. And a SVG
element with a title/desc and role none/presentation would be an author
error and would fail validation. Link to resolution. I will be checking the
affected testable statements on the wiki, but I believe I already fixed
this by removing any title/desc children in an affected test.

Hey Fred, all.

This is to acknowledge your question and indicate I'm adding it to my
list. I'm still syncing up our respective test sets, but am working on
some other WebKit/ARIA-related issues. Do you need an answer this week?
