It appears that Pandoc generates PDF documents via LaTeX. One problem with this is that, as far as I can tell, LaTeX can't generate tagged PDFs. This is an accessibility problem. Granted, for documents that are heavy on math and/or graphics, the point is probably moot. But many technical documents that are distributed as PDFs would benefit from being tagged.

Luckily, LibreOffice can produce tagged PDFs. And unoconv is a convenient utility for doing this from the command line. So you can use pandoc to convert to a format that LibreOffice can consume, then issue a command like this:

    unoconv -f pdf -e UseTaggedPDF=true mydoc.odt

I've tried it, and it works.

Pandoc can convert into ConTeXt which can produce PDF/A (tagging included) easily. Why this can't be done in one command like with xelatex, wkhtml2pdf and what else is supported, I don't know. Many programs can be used to create PDFs but the quality of output isn't always the same.

ConTeXt is supported as well: `pandoc input.md -t context -o output.pdf`
