/**
* AtomCreator03 is a FeedCreator that implements the atom specification,
* as in http://www.intertwingly.net/wiki/pie/FrontPage.
* Please note that just by using AtomCreator03 you won't automatically
* produce valid atom files. For example, you have to specify either an editor
* for the feed or an author for every single feed item.
* Some elements have not been implemented yet. These are (incomplete list):
* author URL, item author's email and URL, item contents, alternate links,
* other link content types than text/html. Some of them may be created with
* AtomCreator03::additionalElements.
*
* @see FeedCreator#additionalElements
* @since 1.6
