attr_status value

I am examining old confd log offline of a Sophos UTM 9 image. It contains an audit trail of firewall rule changes (packet filter class ). A line with "object_changed" has values"attr_status"0" oldattr_status="1
What does this mean? Does this mean that a rule becomes disabled ? My guess would be status 0 is not active, status 1 is an active firewall rule?
