Re: Talk about Payments Accessibility User Requirements at APA call

cc+ the internationalisation folks who also need to review things and have  
thought about this problem.

I don't know of a formal guide, but here are some personal opinions:

Obviously, make the spec conform to WCAG, and try to solve problems that  
are not clearly addressed by WCAG.

For example:

- Zooming the spec significantly (say 5 times, not just the double  
formally required) should still result in something readily legible.

- All images need a description that explains them, which may be part of  
the text itself or linked through e.g. longdesc

- Make sure images are clear, and can be viewed under high contrast - no  
super-fine lines, black on grey, tiny text, and the like. Have a look at  
the tricks I used in  
http://svg-access-w3cg.github.io/use-case-examples/rectrack2-notes.html  
for some clues, but note that, like all SVG accessibility, is a work in  
progress. (If you do work from it as a basis I'd love to get your input on  
doing so).

- Avoid walls of text. Break explanations into manageable chunks, minimise  
jargon, link to definitions of technical terms, and add illustrative  
diagrams.

- Check the stylesheet for adequate contrast. Examples using green text on  
a green background or light text on a light background aren't helpful.

- Don't assume people can deconstruct a written algorithm. Explain the  
effect, and ideally provide a diagram as well.
