Hi Alex, Summary is the equivalent of a text description that can be mapped to accDescription. The summary is not visible to sighted users. So, it behaves the same way as a hidden aria-descibedby. We should start being consistent in the way that we provide information.
Captions are visible labels that have an object associated with them and a
label relation should be used.
We could apply a role of caption to the caption label if we had one. I see
no need for additional methods in IAccessible2Table2.

When I started this thread I assumed that summary and caption are
semantically different than name (label relation) and description
(description relation) and AT wants to have an access to them. If this
makes sense then we should go with VARIANT approach, otherwise summary
and caption should be deprecated. Do we have any use cases from AT
perspective?
Thank you.
Alex.
