The function was added in 5.4, but it makes use of QQmlCustomParser,
which at the moment is private API. This way Qt3D or bleeding edge users
can still use the function, while keeping freedom to change
QQmlCustomParser.
Since 5.4.0 had the typo in the \relates, users won't see a change from
5.4.0 to 5.4.1.
