These types are created (and owned) by the QmlXmlParser and consumed by the

the fields for both its own use and for the use of the upcoming QmlDom API.
The types are part of the generic sounding "QmlParser" namespace for legacy
reasons (there used to be more in this namespace) and will be cleaned up and
migrated into a more appropriate location shortly.
