 If the author name contains any special characters, they might end up in
 the RSS feed unescaped, causing failed feed validation and thus causing
 problems for many readers.

 The code now is:

 <dc:creator><?php the_author() ?></dc:creator>

 Shouldn't this be:

 <dc:creator><![CDATA[<?php the_author() ?>]]></dc:creator>

 Or:

 <dc:creator><?php htmlspecialchars(the_author()) ?></dc:creator>

 This might be a result of a custom author plugin not escaping these
 characters on the way into the database, but Wordpress should handle this
 more robustly to prevent plugin authors from messing things up like this.
