Footnotes are assigned a now deprecated ARIA role (doc-endnote)

[batpigandme]

Currently, footnote items are assigned role="doc-endnote", e.g.

<li id="fn1" role="doc-endnote">

Added with the WAI-ARIA endnotes roles here b062117, the role for individual footnote items, role="doc-endnote" has now been deprecated.

doc-endnote was deprecated in DPUB-ARIA 1.1, so this errors on the assertion that ARIA roles used must conform to valid values (e.g. using axe accessibility checker).

The link above describes the superseding behavior—i.e. that doc-endnotes identifies the containing section as being endnotes (as is already done in pandoc), and then native <li>, or list or listitem roles should be used within (also already done).

I think, then, the fix would just entail no longer adding the role here:

pandoc/src/Text/Pandoc/Writers/HTML.hs

Line 1646 in bb5f0f7

customAttribute "role" "doc-endnote"

Reproducible example:

Can be reproduced with, e.g. the following as input.txt:

---
title: "Title"
---

This is a sentence.[^1]

[^1]: This is a footnote.

and pandoc -s -o output.html input.txt.

pandoc 2.18 on macOS 12.3.1 (or same example run in pandoc try)

Thanks so much for the quick fix!
