No. It does the minimum parsing required to route the messages (header
fields 'sender', 'destination', 'interface', etc.). There is no
validation, except a few incomplete ones in the headers of the message.

I don't know, I need to test that. Is there an easy way to disable
validation in dbus-daemon?
