Re: DL, DT, DD in PDFs

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.
