@mcking65 is this a change we would want to reflect in the APG? |

@smhigley should we discuss your question (should we specify how aria-setsize and aria-posinset should be calculated?) in a WG meeting? |

Oh I guess this is related to your open question. Honestly, i think we might need to explicitly say how it is calculated, because "from the document structure" seems a little to vague to me.
For example, if the tree items are group with divs that don't have role group, I think we should ignore that structure, right? This sentence is not clear about that.

@spectranaut I actually already addressed my open question in this PR 😅: #2104
Which I think might also address your comment? Let me know if you think it needs different wording (though those comments probably belong on the other PR)

@spectranaut I think I've addressed your comments -- would you mind taking another look when you get a chance? |
