Usually not needed if not supported by the underlying filesystem.

You either return default values (which could be specified by the
mount command just as VMS currently does for ISO 9660 volumes) or
in some cases, you return an operation not supported type error.

If you really need to store VMS specific attributes, you can do it
the way NFS currently does by using a small header file containing
the actual attribute data.
