The result

Have a header file with the following code:

namespace mynamespace {
    class MyClass : QObject {
        Q_OBJECT
        Q_PROPERTY(QDeclarativeListProperty<mynamespace::MyItem> myitems READ myitems)
    }
}
// Note that Q_PROPERTY has a type with template and namespace.

Running Doxygen with 'GENERATE_XML=YES' option creates an XML file for the class where the Q_PROPERTY has incorrect name. The file is attached.

Result name: mynamespace
Expected name: myitems
