    XXX

    These types are created (and owned) by the QmlXmlParser and consumed by the 
    QmlCompiler.  During the compilation phase the compiler will update some of
    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.
