Would this be an extension?

chris-little commented 2 years ago

@jerstlouis Arghh! just lost all my typing. Start again.

I think most accessibility options are just styles, or criteria for styles. E.g. alternative or reduced colour palettes, altered contrast and brightness, emboldened lines and other graphical entities. So I do not think these require an extension ( but perhaps some informative text and references).

However, braille, audio, or text to be spoken by a screen reader, could be an extension, or could be subsumed under 'labels'. I can think of no reason why not the latter, but there may be some requirements from them that does require an extension. We will only know when we investigate in more detail.

I think that there may be some clues in the SVG-AMM, but it needs lots of caffeine.

It's worth watching some of the accessibility presentations from the 2020 Maps for the Web workshop.
