Accessibility tree inclusion conditions may need to address css visibility (Comment 361)

Document: WAI-ARIA 1.0 User Agent Implementation Guide Last Call Working Draft 10 January 2012
Part: 5.1.1. Including Elements in the Accessibility Tree (include_elements)

Some browsers do not include elements in the accessibility tree if content is hidden with display:none or visibility:hidden. It is debatable, at least for aria-describedby, whether this is desirable behavior. Currently, section 5.1.1 prescribes that hidden elements that meet the other conditions listed need to be in the tree, which is different from current browser behavior. Either browser developers need to agree to the prescribed behavior or the prescription of this section needs to be modified.

Proposal:

Requires discussion. There is some merit to the idea that there is a need for descriptions that are both structured and not visible. The question is whether ARIA 1.0 can address that need.
