New output formats: XHTML 5, Web Help containing XHTML 5,
EPUB 3, possibly containing rich media.

A new chapter of the manual, "Rich media content",
http://www.xmlmind.com/ditac/_distrib/doc/manual/webhelp/media.html,
explains how to add SVG, MathML, audio, video, Flash animations and
actions (e.g. click some text to play a sound) to your
DITA topics. This chapter also explains how XMLmind DITA Converter
processes this rich media content depending on whether it is
supported by the output format.
