What is the current best method to create an ADA Compliant PDF document using LaTeX and pdftex?

I see postings from 2015 and perhaps even 2018 on this topic. I recognize that some parts of the work include adding pdf titles and other meta-content.

Does someone have the equivalent of a template (header file) that can be used? What precautions must be taken with hyperref links internally and externally? Should this problem instead be pushed off to an off-line validation service (or run through Acrobat Pro)?

I ask as an instructor developing documents for on-line instruction in courses in the USA, where the certification now requires an ADA validation step.

    ADA requires imho tagged pdf, so see https://tex.stackexchange.com/a/550523/2388. – Ulrike Fischer Aug 08 '20 at 16:04
  • @UlrikeFischer Much obliged. Adding pdfinfo content (e.g. via hypersetup) seems to be the easy part. Tagging links is the heavy-lifting part. I have thought naively that href would simply need an [alt=...,tag=...] option but alas I see differently now. I defer that this question could be left open for the best option to build the pdfinfo header or simply closed as a duplicate to the one that you referenced. Thanks! – Jeffrey J Weimer Aug 08 '20 at 16:28
  • @JeffreyJWeimer You should not add pdfinfo via hypersetup. You must add XMP metadata, i.e. through hyperxmp. – tanGIS Aug 11 '20 at 05:52
