"Safety-Critical QML Types" has a confusing line

doc link : https://doc.qt.io/QtSafeRenderer/qtsr-qml-types.html

The Safety-Critical QML Types says:

To include these to your application, you must add them to Qt Quick UI Forms (.ui.qml files).  

Now, it's a bit confusing if the user can also use a .qml file, not a .ui.qml file, because technically, .ui.qml and .qml should not have mucn difference. But since the sentence has "must" in it, it gives an impression that the user also "must" use .ui.qml files.
If that's correct, the sentense should be like this:

To include these to your application, you must add them to Qt Quick UI Forms (.ui.qml files), not QML files(.qml files).   

or if the user doesn't necessarily use .ui.qml files, the sentense should be like this:

To include these to your application, you must add them to QML files (either .qml or .ui.qml files).
