There are significant differences between HTML and PDF tags. Items like lists, tables, footnotes, indexes, tables of content, and many others either don't exist in HTML at all or are vastly different.

Bottom line: a PDF isn't anything like an HTML webpage, and neither are PDF tags.

Hello,
If the HTML is properly tagged, why is there any question about the PDF?
Isn't it almost a direct conversion? I've never programmed PDF, but from what I've seen with my screen reader, PDF tags and HTML tags are almost identical.
Thanks,
