Exactly as described, this is the standard SNMP RowStatus control used to create or destroy a row in this EMIX sequence table. Because a sequence with a nonzero reference count can't be safely removed while still in use, attempting to set this to destroy on a heavily-referenced sequence is the action that would need those references cleared first, tying this object directly to the sequence's own reference-count object. For example, setting this to createAndGo along with a fresh sequence string and name in the same SNMP request is how an operator defines an entirely new custom EMIX pattern from scratch.
