Re: Missing support for scope="rowgroup" attributes within tables

Hello John,
Poor support for the scope attribute is not new.
Window-Eyes never supported the scope attribute.
See http://www.w3.org/WAI/WCAG20/Techniques/ua-notes/html#H63
Till a few versions ago, even JAWS' support for rowgroup was lacking
and this is embodied in the first sentence of the above user agent
notes.
I had written to Apple Accessibility team over a year ago covering a
handful of issues including poor support for the scope attribute.
The bug reporting process was very inaccessible which Apple
acknowledged and accepted the email filing.
In 2013, NVDA would not honor headers-id method if the headers
attribute referenced a TD cell with an id ... valid in HTML4. See NVDA
bug #3244.
(and by extension, td with a scope attribute) ... they said it is a
Firefox issue.
So I had filed a bug with Firefox too (881048 ).
HTML 4 recognizes that in reality in complex tables it is not
possible to always markup all header cells as TH. So an id or scope on
a TD cell is permissible and this is documented. But this is illegal
in HTML5 which is a problem. I have noted this before on other lists
too.
It is fine if one can mark up all header cells as TH. But when one is
constrained, id or scope on TD cells should be alright.

Thanks and regards,
Sailesh
