I can't remember the rules here - can I put a block element like a paragraph in an li? Or actually, now that I think about it, probably what would be better would be to use a definition list - which means I'd want to put my p tags in the dd tag.

What I'm wanting to do is create a kind of glossary. The dt tag would hold the type of item, and the dd would be the actual note about the item. The notes may have more than one paragraph, though, which is the reason for the question. If I can't use p tags, what's the best solution? A span that's styled like a p?
