+    \since 4.7
+    \class QDeclarativeExtensionPlugin
+    \brief The QDeclarativeExtensionPlugin class provides an abstract base for custom QML extension plugins.
+
+    \ingroup plugins
+
+    QDeclarativeExtensionPlugin is a plugin interface that makes it
+    possible to offer extensions that can be loaded dynamically into
+    applications using the QDeclarativeEngine class.
+
+    Writing a QML extension plugin is achieved by subclassing this
+    base class, reimplementing the pure virtual registerTypes()
+    function, and exporting the class using the Q_EXPORT_PLUGIN2()
+    macro.
+
+    QML extension plugins can be used to provide either application-specific or
+    library-like plugins. Library plugins should limit themselves to registering types,
+    as any manipulation of the engine's root context may cause conflicts
+    or other issues in the library user's code.
+
+    See \l {Tutorial: Writing QML extensions with C++} for details on creating
+    QML extensions, including how to build a plugin with with QDeclarativeExtensionPlugin.
+    For a simple overview, see the \l{declarative/cppextensions/plugins}{plugins} example.
+    
+    Also see \l {How to Create Qt Plugins} for general Qt plugin documentation.

+    this to call qmlRegisterType() for all types which are provided by the extension
+    plugin.
+
+    The \a uri is an identifier for the plugin generated by the QML engine
+    based on the name and path of the extension's plugin library.
