The string used to obtain the volume class with g_volume_get_identifier().
Known volume classes include device, network, and loop. Other

This is intended to be used by applications to classify Gio.Volume
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.
