AXAttributeConstants.h and NSAccessibility.h appear to be confused about
these attributes: AXColumnTitles, AXColumnHeaders and AXHeader.
AXColumnTitles is described in AXAttributeConstants.h as obsolete or
unknown, but it appears in NSAccessibility.h and its documentation without
qualification. It is in fact used in NSBrowser, but it does not appear to be
used in NSTableView or NSOutlineView.
AXColumnHeaders used to be found somewhere in the headers, but I don't see
it any longer. It would seem to cover the same concept as AXColumnTitles,
which see above. Maybe I was thinking of AXColumnHeaderUIElements, which
does appear in AXAttributeConstants.h but not NSAccessibility.h. It is
described nowhere in the documentation and I don't see it used in browsers,
tables or columns.
AXHeader appears both in AXAttributeConstants.h and NSAccessibility.h, and
it is actually used in NSTableView and NSOutlineView (that is, in the column
object). It is not used in NSBrowser.
Is all this intended? That is, AXColumnTitles applies only to browsers,
AXColumnHeaders and/or AXColumnHeaderUIElements is obsolete/deprecated, and
AXHeader applies only to table and outline columns?
I understand how this might reflect implementation details of browsers,
tables and outlines and their respective concepts of columns. But it doesn't
make sense to me from an accessibility point of view. Surely a user
(disabled or not) thinks of columns and their titles/headers as being the
same thing in browsers, tables and outlines.
