  * - a headline mentioning the contribution
  * - the full content of the section
  * - a button linked to the section
  * - a link to the containing section, if any
  *
  * Note: this function returns legacy HTML, not modern XHTML, because this is what most
  * e-mail client software can afford.

  * @param array attributes of the item
  * @param object overlay of the item, if any
  * @return string text to be send by e-mail
