++ \brief The MapCopyrightNotice item displays the current valid
++ copyright notice for a Map element.
++
++ This object can be used to place an additional copyright notices
++ programmatically.
++
++ Note that declaring a MapCopyrightNotice inside a QtLocation::Map element
++ is not possible, like for any other QQuickItem.
++
++ The release of this API with Qt 5.9 is a Technology Preview.
