	 * <li>downloadversion</li>
	 * <li>flashversion</li>

	 * <li>multimediaversion</li>

	 * representing {@link MediaItemPageVersion} is NOT allowed. A media item page version is a media item
     * which references a page version, and in context of its workflow it should be seen as a page version.
	 * 
	 * @return Array of domain prefixes. An empty array represents that the constraint is designed for all
	 *  known workflow enabled content domains. Must not return <code>null</code>.
