 * Error domain for errors generated by a remote message bus.
 *
 * Errors in this domain will be from the [error@Gio.DBusError] enumeration.
 * See [type@GLib.Error] for more information on error domains.
 *
 * Note that this error domain is intended only for
 * returning errors from a remote message bus process. Errors
 * generated locally in-process (for example, by [class@Gio.DBusConnection])
 * should use the [error@Gio.IOErrorEnum] domain.
