Doxygen supports XMLDoc, JavaDoc and several other documentation styles. JavaDoc style has comments that comply with style(9), and is therefore preferred over XMLDoc which uses "///" for its documentation comments, which is not ANSI-C compatible. JavaDoc is also familiar to anyone who has used tools like PHPStorm for webdev in the past.
