+ *   mappings defined in the unlabeled module.
+ *
+ *   Required attributes:
+ *
+ *     NLBL_UNLABEL_A_ACPTFLG
+ *
+ * o LIST
+ *   This message can be sent either from an application or by the kernel in
+ *   response to an application generated LIST message.  When sent by an
+ *   application there is no payload.  The kernel should respond to a LIST
+ *   message with a LIST message on success.
