Documentation standard: considerations for accessibility

I know we have just begun to have some standards for our documentation [1].

As I am preparing the Hands-on Kernel Lab [2] for contribution, it came to
mind that my screen captures of qemu are not helpful to our visually
impaired colleagues using screen readers. I thought I would start this
thread so we can contemplate accessibility as part of our standards.

A quick search led to [3], which as I suspected suggests adding alt-text to
summarize what an image is trying to show. I doubt full-text of the qemu
log would be appropriate, but perhaps calling out the specific lines that
are of interest?

There are other suggestions in [3] about font styling and so on that are a
bit harder to see an easy path forward on. Perhaps an accessible rendering
that skips the fancy styling?

Obviously this is not a well-thought out proposal. I just thought we could
start a conversation.
