Hello and thank you for raising these issues.

Note that there is a free and very good PDF accessibility checker:
http://www.access-for-all.ch/en/pdf-lab/pdf-accessibility-checker-pac.html
You can easily generate a detailed report with this tool. It does, however,
not check for PDF/A-1a conformance.
