* <li>The Extension Property - It is also defined in extension definition
 * file. It provides the name, data type, display name key and so on, as the
 * system property works for the Model-defined element.
 * <li>The Extension Model Property - It is defined by {@link IReportItem},
 * instead in extension definition file. <code>IReportItem</code> defines its
 * own dynamic model. The extension model property definition is defined by
 * {@link IPropertyDefinition}. The dynamic model means the extension element
 * can switch from one set of extension model properties to another under some
 * case. They can be serialized to an XML-type extension property when saving to
 * design file, and deserialized from this XML-type extension property when
 * loading design file.
 * </ul>
