In debug builds with "embedded tests" enabled, these will automatically be used as input for the message-internals test. Some of the messages themselves are output from a fuzzer, others are simplifications to include only one reason for lack of validity per message. I've included an annotated hex-dump for each message here, but the dbus test suite doesn't currently know how to convert hex to binary, so I've also committed the corresponding binary. See the comment at the top of each hex-dump for how to create the binary version (which requires the xxd tool shipped with vim). It would be nice for the dbus test suite to be able to convert the annotated hex-dump to binary, either at build-time with a Python script or at runtime by loading the text file and decoding the hex, but I don't want to block on that for dbus/dbus#413 and dbus/dbus#418.
