Here comes 1194.22 d, as in Devo, mapping 1194.21 to iso 9241-171

Summary: ISO does have nice definition of "information about a UI element". Theirs covers general and ui class states (selection ,focus, position, etc), attributes, values, and relationships. We could consider adding this to the teitac language in the context of the refresh.
Unlike d) Iso has the reference to images in 8.6.6 (Provide user interface element descriptions), and 8.2.1 (Provide a name for each user interface element), separate from the main "info" section. Same info, different structure...

(d) Sufficient information about a user interface element including the identity, operation and state of the element shall be available to assistive technology. When an image represents a program element, the information conveyed by the image must also be available in text.

(ISO) 8.6.4 Software shall provide assistive technology with information about individual user interface elements, using methods compatible with 8.6.3, except elements that only serve as an integral portion of a larger element, taking no input and conveying no information of their own.
NOTE 1 User interface element information includes, but is not limited to: general states (such as existence, selection, focus, and position), attributes (such as size, colour, role and name), values (such as the text in a static or editable text field), states specific to particular classes of user interface elements (such as On/Off, depressed/released),and relationships between user interface elements (such as when one user interface element contains, names, describes, or affects another). This applies to on screen user interface elements and UI status values such as toggle keys.
NOTE 2 User interface element information is typically available to users by inspection or interaction. Users with certain disabilities may not be able to see or otherwise detect this information without using assistive technologies.




I am also pasting in 8.6.3
8.6.3 Use standard accessibility services
Software that provides user interface elements shall use the accessibility services provided by the system to
cooperate with assistive technologies. If it is not possible to comply with 8.6.6, 8.6.6, 8.6.7, 8.6.8 and 8.6.9,
using these means, the software shall use other services that are supported, and publicly documented, and
implemented by assistive technology.
NOTE 1 In many cases the standard user interface elements provided by platform software already make use of
the accessibility services, so the application only has to explicitly use the accessibility services when it uses non-standard
user interface elements.
NOTE 2 Assistive technology may be running on the same system or on a separate system from the application
software.
