I found strange behavior in validate_selinuxuser. Perhaps it's material for another ticket.

Obviously extra info should not be allowed. Is "s5-s1" or "c4.c3" valid? Can the first value be higher than the second? AFAIK (I'm not an expert though), MCS doesn't allow dashes, so "c0-c4" should not be allowed. Chains like "c1.c2.c3" also don't look right.
... Also, the MLS/MCS numeric limits are not enforced correctly: "xguest_u:s92:c999999999,c0" passes.
