Evidently, there is no KnowledgeBase entry for this type of reported issue. Here are the currently-supported entries (do you see a good fit for "The landmark must have a unique aria-label, aria-labelledby, or title to make landmarks distinguishable"?): https://github.com/daisy/ace/blob/5d4cc866af8141180980522748c0aa82830afb7a/packages/ace-report-axe/src/index.js#L19-L75

The message "The landmark must have a unique aria-label, aria-labelledby, or title to make landmarks distinguishable" comes from the landmark-is-unique check:

Charles, could you please share the EPUB so we can reproduce the exact Axe check/rule at our end? Thank you!

[clapierre]

@danielweck I will check with the publisher and send you the EPUB directly once they approve. Thanks

[laudrain]

@danielweck yes it comes from the rules of uniqueness of landmarks, but as I stated in issue 271, I cannot find any exhaustive list of landmark roles !
