+If Mandatory Access Control, or

+is enabled in your kernel,
+then in addition to the traditional credentials,
+each subject
+(typically a user or a socket)
+and object
+(file system object, socket, etc)
+is given a
+.Em MAC label .
+The MAC label specifies the necessary subject-specific or
+object-specific information necessary for a MAC security policy
+.\" .Xr ( mac 9 )
+to enforce access control on the subject/object.
+.Pp
+The format for a MAC label is defined as follows:
+.Dl Sy policy1 Ns No / Ns Sy qualifier1 , Ns Sy policy2 Ns No / Ns Sy qualifier2 , Ns ...
+.Pp
+A MAC label consists of a policy name,
+followed by a forward slash,
+followed by the subject or object's qualifier,
+optionally followed by a comma and one or more additional policy labels.
+For example:
+.Pp
+.Dl Li "biba/low(low-low)"
+.Dl Li "biba/high(low-high),te/equal(equal-equal),partition/0"
