Thanks Pablo,

I managed to patch the files (I don’t have lpdf-tag-imp-testing.lmt but patched lpdf-tag-imp-mkiv.lmt instead, as well as lpdf-tag.lmt), and Acrobat finds the tags and is able to read the math. This will need some work, in order to have variables and symbols to be read properly, but it is a very promising beginning.

You should be aware that while alt is better than nothing, it has lots of problems. E.g. for braille displays it is typically much too verbose. There is nice presentation from Neil Soiffer here that demonstrate the benefits of mathml: https://www.youtube.com/watch?v=ja7gjDCN8n8&t=1201s -- Ulrike Fischer http://www.troubleshooting-tex.de/
