Hi,
Please note that the PDFs produced by ConTeXt when tagging is enabled are
still some steps short of being PDF/UA compliant. You can check this with
the freely available "PDF Accessibility Checker". (Just google for it.)
Nevertheless, ConTeXt is the only TeX-based option that supports PDF
tagging and it does a good job - thank you Hans for your efforts.
