	 * Duplicates the extension identifier. The extension identifier must be set

	 * property values cannot be right.
	 * <p>
	 * The extension identifier is:
	 * <ul>
	 * <li>EXTENSION_ID_PROP for Oda elements.
	 * <li>EXTENSION_NAME_PROP for extension elements like chart.
	 * </ul>

	 * @param destination
	 *            the destination element
	 * @param sourceModule
	 *            the root module of the source
