+
+    The MapObjectView is used to populate Map with map objects, either from a model or via
+    \l addMapObject or \l removeMapObject.
+
+    The MapObjectView type only makes sense when contained in a Map, meaning that it will not work when added inside
+    other QML elements.
+    This can also be intended as an object layer on top of a Map.
