Listbox role: clarification about Accessible Name Guidance

[kantoche]

Hi,

In the article Providing Accessible Names and Descriptions, Listbox role has its Necessity of Naming equals to "Required"
See: https://www.w3.org/WAI/ARIA/apg/practices/names-and-descriptions/#accessiblenameguidancebyrole),

But in the design pattern Listbox, we can read : "If the element with role listbox is not part of another widget, such as a combobox, then it has either a visible label referenced by aria-labelledby or a value specified for aria-label." So, in this case the Necessity of Naming should not be "Required".
But there is no status of Necessity of Naming corresponding to a name provided by a previous or a parent content as it should be the case with a combobox.
See: https://www.w3.org/WAI/ARIA/apg/patterns/listbox/

So, could you clarify this issue?

Related to w3c/aria#1725. This is a valid APG issue.

There is also open APG issue #2290

The ARIA Authoring Practices (APG) Task Force just discussed Listbox naming guidance.

<jugglinmike> Topic: Listbox naming guidance
<jugglinmike> github: https://github.com//issues/2856
<jugglinmike> Matt_King: Listbox *does* require a name in ARIA, but in a composite like a combobox, we don't require a name on the element itself.
<jugglinmike> Matt_King: I think this is in part an ARIA question, not just an APG question
<jugglinmike> jamesn: I believe there's already an issue for this
<jugglinmike> jamesn: Maybe I'm misremembering, though
<jugglinmike> Jem: Should we transfer this to ARIA, then?
<jugglinmike> Matt_King: We might need a separate issue for ARIA
<jugglinmike> Matt_King: We got some feedback on this issue, but that was back in the 1.1 combobox days when these things were separate
<jugglinmike> jamesn: Is it easiest to recommend a name on the listbox in this case, even though it's redundant?
<jamesn> previous issue was https://github.com/w3c/aria/issues/1725
<jugglinmike> Matt_King: I'll take this issue
<jugglinmike> Matt_King: I'm going to label this as an inaccuracy; I believe this is all editorial
<jugglinmike> Jem: this is related to issue 2290
