I am making accessible a rather long Pdf that includes a 10 page
³Glossary².
I am restricted to the PDF file and Acrobat, and I cannot revert to the
original (Word?) document.
The Glossary section was generated as a series of paragraphs, one per
glossary item. Not even a list.

Now I can (laboriously and manually) create a List structure for the
Glossary items, but I wondered about using ³dl², ³dt², and ³dd² tags.
If this were an HTM document that is what I would use here.
Is that the preferred solution for PDF files as well? Will it make a
difference to assistive technology reading the PDF?

Your advice most appreciated!
Alan

Within one or more <L>/<LI> structures (of course), use <Lbl> tags for the term and <LBody> tags for the definition.

So I gather there's no point in using the dl/dt/dd semantics or no way to do so with the PDF. Gotcha.Thanks!

It’s true there’s no point in using dl/dt/dd as structure elements (unless you are going to map them appropriately, which sort of loses the point in a different way). However, there _is_ a way to do definition lists with PDF, as I indicated. It’s as capable as HTML's <dl> model, and actually, more general and flexible. Sadly, support for this feature of PDF is uneven.
