The string used to obtain the volume class with g_volume_get_identifier().
Known volume classes include device, network, and loop. Other
classes may be added in the future.
This is intended to be used by applications to classify GVolume
instances into different sections - for example a file manager or
file chooser can use this information to show network volumes under
a "Network" heading and device volumes under a "Devices" heading.
