What tags are permitted in Feed/Stream Stories?
You can include only plain text content in Feed/stream stories; they cannot contain any HTML or FBML tags.
However, you can include
fb:intl and its child Internationalization tags as well as rich media like images, Flash, and MP3, which get rendered in the attachment parameter that you include when you call stream.publish, Facebook.streamPublish, or FB.Connect.streamPublish.
