There is a relatively recent experimental package for LaTeX that may be of interest to you: CTAN: https://www.ctan.org/pkg/tagpdf GitHub: https://github.com/u-fischer/tagpdf The package is maintained by Ulrike Fischer, who is very active in the TeX community. However, the package description says: > The package offers tools to experiment with tagging and accessibility > using pdfLaTeX and LuaTeX. It isn't meant for production but allows > the user to try out how difficult it is to tag some structures; to try > out how much tagging is really needed; to test what else is needed so > that a pdf works e.g. with a screen reader.
