RE: ACTION-1422: Develop proposal for label role and aria-labelfor property

How would this work for something like an edit field, if no explicit association is provided?

 

Thanks,

Bryan

Hi Matt,

don't think that aria-labelledby should be required. UAs don't require an explicit mechanism to identify the labelled element.

for example:

<figure>

<figcaption> caption <figcaption>

</figure>

figure is labelled by figcaption so an author should be able to add


<figure>
<figcaption role=label> caption <figcaption>
</figure>

Per discussion in the ARIA meeting on April 21, there was consensus to drop the proposal for an aria-labelfor attribute to go with the new role label. The group did not identify any specific benefits of an aria-labelfor that are not provided by aria-labelledby. 

Proposed specification text for role label follows. 

Label 

An element containing content that labels another element. A label MUST have an explicit relationship with the element it labels expressed with aria-labelledby on the element being labeled. 

The most common accessibility API mapping for a label is the accessible name property. However, because aria-labelledby is required to create the labelling relationship, use of role label on an element does not change the accessible name computation of the element to which the label applies. 

Authors are not required to use role label to identify elements that serve as a label but may do so in order to provide semantic clarity in code.
