It says to make sure that source files pass external accessibility checks. For EPUB source files it says to use the the ACE Accessibility Checker from the DAISY Consortium. But does not indicate which accessibility features, if any, will be made available to readers on the Kindle platform. I know that Amazon's conversion to KFX format for Enhanced Typesetting ignores almost all non-visible HTML content in the source document so added accessibility markup won't actually make it to reading apps and devices.

It states that books should be tested using the Kindle Previewer and discourages testing on actual devices,
Over my dead body....

but as far as I can tell the Previewer provides no method for testing of accessibility features. For example, use of alt text for images is encouraged in the Guidelines, but I don't see any way to view them in the Previewer.

Listing markdown as an accessibility option for authors is really grasping at straws.

(Unrelated, but I noticed that the Guidelines has lots of broken links to EPUB specs at the now defunct idpf.org site.)
Yes, I noted the myriad broken links some months back. It's annoying.
