LastPx and LastShares are not required fields in ExecReport if ExecTransType=STATUS. That is probably because some may consider status report as an overall status of an order only and others in addition to that would use it to show last action on an Order. Second ones would want to use LastPx and LastShares which will equal those in last active execution, and it is safe for them because they probably don’t consider status report as an active execution. First ones wouldn’t need to set these fields at all (they are not required) or have them be 0, wich will work fine even for those who look at status report as at execution.
So, I think, same thing should be with ExecType. It should not be required for ExecTransType=STATUS. In addition, it might be usefull to have extra "Status" value of ExecType for those who look at status report as at execution
