+    \qmltype MapParameter
+    \instantiates QDeclarativeGeoMapParameter
+    \inqmlmodule QtLocation
+    \ingroup qml-QtLocation5-maps
+    \since Qt Location 5.9
+
+    \brief The MapParameter type represents a parameter for a Map element.
+    This type provides a mean to specify plugin-dependent optional parameters
+    for a map.
+
+    MapParameters by default contain only the \l type property, and
+    are highly plugin-dependent.
+    For this reason, additional properties have to be defined inside a
+    MapParameter at declaration time, using the QML syntax "property var foo".
+
+    What properties have to be put inside a particular MapParameter type for
+    a particular plugin can be found in the documentation of the plugin.
+    Note that MapProperties are \b optional.
+    By not specifying any of them, the Map will have the default behavior.
+
+    The release of this API with Qt 5.9 is a Technology Preview.
