RE: “I didn’t quite understand what you were suggesting should change, did you mean that it should always be available with the icon, rather than before it?”

I am suggesting the text description accompany all instances – if those instances are flow content.

I am fine with the example where the usage is clustered within a data visualization component. However, in a chart or map, it would have to be a legend, since there is likely no “first instance” as visually interpreted.

Hi Charles,

Discussion here is fine ☺

I didn’t quite understand what you were suggesting should change, did you mean that it should always be available with the icon, rather than before it?

A scenario we were considering was that icons can be used as categorisation and used repeatedly in table rows/columns, for example:
[alt = a table of cases in a bug tracker, the first column shows an icon for ‘bug’ (spider), ‘idea’ (light bulb), and email (envelope).]

In scenarios like data-visualisations or maps, it seemed reasonable to allow for a legend approach rather than require something on every instance.
It would also help keep it cross-technology, as things like ePub/PDF wouldn’t (reasonably) be able to have a page-level toggle.

> This also assumes the “page” is the user’s context.

Yep, this is for WCAG 2.x, so the page is the unit of conformance.
