Nfc Docu error in text and not detailed enough

In the docu of the QNearFieldManager there is text saying:
QNearFieldManager *manager = new QNearFieldManager;
manager->registerNdefMessageHandler(this,
SLOT(handleNdefMessage(QNdefMessage,QNearFieldTarget)));

I guess this should be
QNearFieldManager *manager = new QNearFieldManager;
manager->registerNdefMessageHandler(this,
SLOT(handleNdefMessage(QNdefMessage,QNearFieldTarget*)));

else it results in an runtime Signal-Slot warning.

Also nowhere in the NFC documentation can be found which platforms are currently supported. You can only find out wheter the platform you are using supports the QtNfc module by using the QNearFieldManager isAvailable function. Maybe this should be documented somewhere. The documentation NFC is general not as detailed as I know it from the rest of Qt.
