BOSA Accessibility Check is a client-side JavaScript application that checks a HTML document or source code, and detects violations of a defined coding standard. Comes with standards that cover the three conformance levels of the W3C's Web Content Accessibility Guidelines (WCAG) 2.1 and the U.S. Section 508 legislation.
We'll need to write, next to the Readme, a more elaborate document describing the relationship of this tool vs the WCAG and EU guidelines, since it inherently cannot cover 100% of the accessibility rules (for example, it can only validate if there's a filled in alt-tag on an image, not if the content of that alt-tag is an accurate description of the image, same for form-labels.
@stefanruijsenaars note: this is likely a task we will outsource to someone else, your talents are better used in developing the tools than in documenting accessibility guidelines :)
