There is some discussion going on related to "well tagged pdf" if
list item bodies are paragraphs or not.

Basically the answer is, "it depends":
In lists with short topics you don't want a paragraph tagging, but
you do in long list items with multiple paragraphs.

We will probably have to offer more control for users here.

But imho as *default* it makes more sense if tex4ht doesn't insert
paragraphs, but offer some command that allows to mark list item
bodies as real paragraphs. Lists with short, non-paragraph items are
more common than lists with long texts.
