Same code does not report the same error (nav epub:type toc not mapped to ARIA role doc-toc)

[editadapt]

Using ACE GUI 1.1.2 on windows 10 I have this error reported:
Minor | Best Practice | epub-type-has-matching-roleVia: aXe | nav.xhtml#epubcfi(/4/2[toc])<nav xmlns="http://www.w3.org/1999/xhtml" xmlns:epub="http://www.idpf.org/2007/ops" epub:type="toc" id="toc"> | Element has no ARIA role matching its epub:type Ensure the element has an ARIA role matching its epub:type ARIA role should be used in addition to epub:type

Strange behaviour because it does not happens on all epub checked. Here are two document code exemples, only document 2 triggers the error in ACE:

• in document 1 i have no violation reported by ACE, code is:

 <nav epub:type="toc" id="toc">
      <h1 id="toc-title">Ariel</h1>
      <ol class="toc">
        <li id="toc-li-1">

• in document 2 i have violation reported by ACE, code is:

<nav epub:type="toc" id="toc">
      <h1 id="toc-title">Índice</h1>
      <ol class="toc">
        <li id="toc-li-1">

Documents are copyrighted so i can't attach them here.

looks like accented characters may be the issue here?

I can confirm the error was reported on two files wich both have accented character <h1 id="toc-title">Índice</h1>

But i believe the error should be reported on all files (with or without accented characters).

Ace App (aka "GUI") ships with Ace 1.2.x-beta, so the results should be equivalent when running Ace via the command line: npm install -g @daisy/ace@next (to install the Ace executable globally), or npx @daisy/ace@next /PATH/TO/BOOK.EPUB (to run it temporarily without installing it).

Could you please privately share the EPUB with me? ( [email protected] )
I'd like to understand the broader publication structure.

Hello, I am testing the latest build of Ace which has been significantly updated. I see that the Navigation Document of Ariel - José Enrique Rodo.epub has epub:type="toc" but no role="doc-toc". The reported error seems normal to me, if I interpret the specifications correctly (this is a "minor" ARIA best practice in the severity classification).
I see the exact same "error" in El yo y el ello – Sigmund Freud.epub, but there are also many more similar epub-type-has-matching-role errors in other XHTML publication documents (for example epub:type=noteref which should be accompanied with role=doc-noteref.
Specifications:

https://www.w3.org/TR/dpub-aam-1.0/#mapping_role_table
https://w3c.github.io/publ-cg/guides/aria-mapping.html#mapping-table

I am closing this issue as "fixed". Feel free to continue the discussion and / or re-open if you wish.

Ace "next" will be released shortly, I am running further tests at the moment.
