Here's a patch I'm using with an MLS version of glipper to give the

Here is a revised patch. I support including this in refpolicy as it's
generally useful for supporting selection managers.
Note that the access_vectors definition is at the end of the file in
this patch. Not sure if the ordering matters in that file, if it
doesn't you can move this to coincide with the other X classes.
