+
+This attribute DOES NOT reflect a replicant's internal status, i.e. if it is
+properly replicating from a master and has not fallen too many seconds behind a
+reliability threshold.  For that, use L</is_replicating>  and L</lag_behind_master>.
+Since the implementation of those functions database specific (and not all DBIC
+supported DBs support replication) you should refer your database-specific
+storage driver for more information.
