I've added some late-in-the-day thoughts...
The following document gives a short overview how xml structural information can be applied to pdf. The document contains also a list of elements that should be tagged (see table 1) https://pdfs.semanticscholar.org/9a51/cd67046a81d4e02d6b4b35fa402bacc892f8.pdf
That looks a bit dated, since the latest PDF version that it refers to is 1.4. You can get better tables of PDF Tag names in the free version of the ISO 32000-1 PDF standard that you can download from the Adobe web site.
PAC 2 - PDF Accessibility Checker (PAC 2) PAC is an easy to use tool to check if your pdf document is accessible. If not PAC will show you the problems in the structure as well as inside the document. http://www.access-for-all.ch/en/pdf-lab/pdf-accessibility-checker-pac.html
Fine for checking one file at a time, but it has a few minor bugs. I don't expect it to be updated, though, since there's now a commercial product available that's obviously based on PAC 2.
And last but not least the pdf specification document. I didn't read the document yet. I try to get my hands on it in the next days. ISO 14289-1:2014 - Document management applications -- Electronic document file format enhancement for accessibility -- Part 1: Use of ISO 32000-1 (PDF/UA-1) https://www.iso.org/standard/64599.html
AFAIK, you can't get this ISO standard for free. Additional PDF/UA resources:- PDF/UA Technical Implementation Guide: Understanding ISO 14289-1 (PDF/UA-1):
