Re: 1.4.3 & 2.4.7: evaluation while blind

I don't see how a blind person can test several others, such as 1.3.1 Info and Relationships. That SC requires you to assess the visual presentation and check if the information and relationships are conveyed programmatically. How can you do that if you can't see it?

There are others like 1.3.2 Meaningful Sequence. If you can only perceive the programmatic reading sequence and not the visual sequence, how can you tell if it is correct?

And 1.4.1 Use of Colour. How can you tell if colour alone is being used? It might be possible by analysing the styles, but that won't work if the colour is in images.

I won't labour the point, but if you can't perceive something, how can you know if there is anything to perceive?

On the same topic, I suspect 1.4.10 Reflow, 1.4.11 Non-Text Contrast and
1.4.12 Text Spacing may also prove challenging. As might 4.1.3 Status Messages (due to the very nature of the failure itself having things not announced by AT, and potentially disappearing completely from the DOM before an AT user can go through the page to verify if any such status was displayed but not announced).
