What markup is allowed in the description of a facebook feed post?

Upon playing with it, it appears that the description for a facebook feed post made by an application can have some html in it. All I've found that works is <b> and <i> but even <br> doesn't work. What sort of formatting is allowed? Or at the very lea开发者_开发知识库st how can i start a new line?

For the record, <i>, <b>, <small> and <center> at least work. They only want you to use inline markup, but as a hack you can put <center></center> to make line breaks.

I think this is it: http://www.facebook.com/notes_cheatsheet.php
