+    \qmlclass Bind QmlBind
+    \brief The Bind element allows arbitrary property bindings to be created.
+
+    Sometimes it is necessary to bind to a property of an object that wasn't
+    directly instantiated by QML - generally a property of a class exported
+    to QML by C++.  In these cases, regular property binding doesn't work.  Bind
+    allows you to bind any value to any property.
+
+    For example, imagine a C++ application that maps an "app.enteredText" 
+    property into QML.  You could use Bind to update the enteredText property 
+    like this.
+    \code
+    <LineEdit id="myTextField" text="Please type here..." />
+    <Bind target="{app}" property="enteredText" value="{myTextField.text}" />
+    \endcode
+    Whenever the text in the LineEdit is updated, the C++ property will be
+    updated also.
+
+    If the bind target or bind property is changed, the bound value is 
+    immediately pushed onto the new target.

+
+    Simple bindings are usually earier to do in-place rather than creating a
+    QmlBind item. For that reason, QmlBind is usually used to transfer property information
+    from Qml to C++.
