+	  This option selects support for Trusted Security Event
+	  Modeling (TSEM).  TSEM implements the ability to model
+	  the security state of either the system at large or in a
+	  restricted namespace on the basis of the LSM security
+	  events and attributes that occur in the scope of the model.
+	  The model may be implemented either in the kernel proper
+	  or exported to an external Trusted Modeling Agent (TMA).
+	  If you are unsure how to answer this question, answer N.
