IsPassive 

A passive segment is a segment that isusually present in GDS PNRs
as a placeholder for an item in the itinerary that does not result ina ticket
being issued by the GDS and for reservation that was not made directly in the
GDS. By extension, all segments that were booked in another system and added to
a booking for centralised management or system synchronisation can be marked as
passive (@IsPassive="true"). This may impact or rigger specific synchronisation
processes. To ensure that a segment is not passive, this attribute should be
set to true. If this attribute is not set, passive information remains unknown
or is not relevant because all segments are of the same
type.
