Simon has folded in the ability to add HTML to comments on his weblog, but he's not going to let you mess up his site, or invalidate his code. Thanks to a php based xml parsing class he is validating his comments and limiting the allowed tags and attributes. The implementation may be strict, but in a way it's quite liberating because you can sit there and code out all the paragraphs, blockquotes and list items you want, and do so with the confidence of knowing that if you forget to close a tag, a detailed report will be provided outlining what needs to be corrected. Check out the requirements he was working with and more details on the implementation at his post about it.
