I agree with Paul that PDF generation and meeting the WCAG 2 accessibility requirements for PDF output are a real problem.
I'm not a real expert on accessibility, but did lots of reading about 2 years ago regarding the issue of creating accessible PDF files from TeX/LaTeX source. As of then - this was a big problem starting to get serious attention from some of the central TeX/LaTeX development people and members of TUG. However, from what I understand (and I have not been following carefully) progress is very slow. I doubt that creating WCAG compliant PDF files automatically is currently possible without very significant amounts of manual effort. Thus, getting WW's automatically generated PDF files to be WCAG complaint is probably currently not feasible.
If that understanding is correct, then institutions which are legally bound to provide only WCAG compliant web services would probably be better off at least disabling PDF generation. Maybe we can add a site+course level control setting to at least disable student access to the "links" to request the PDF generation.
Below is an copy of something I wrote back in 2018:
The TeX User's Group (TUG) and the greater TeX/LaTeX community is well aware of the challenged posed by accessibility standards to the ongoing use of LaTeX.
Dr. Ross Moore recently published a letter with a 5 year plan for the TUG accessibility working group together with academic publishers to gradually improve the accessibility of PDF files generated using (pdf-)LaTeX.
It seems that his plan is focused on cooperation with the publishing community for the first 3 years. (They are more directly on the "front-line" than the authors themselves.) Work on creating documentation to help authors make their own contents is deferred to years 3-4 of the plan, and release of better accessibility packages to the public to year 5. As such, it will be quite a while before regular authors can start to make independent use of the additional features/packages/tools to make their PDF output accessible.
Ross Moore's letter about this is attached; it was downloaded from:
Note: the very end of the letter Dr. Moore addresses the expected future (PDF-UA/2) requirement that included mathematics be described by use of MathML tagging. He envisions this as something to work on in the more distant future (after completing work on the "text level" accessibility of LaTeX generated PDF files).
Bottom line: there is a long way to go before we can expect PDF material created using LaTeX to be compliant with accessibility standards.
