1) "At many airports, aeroway=taxiway is also used within apron areas, however". Unless the apron is divided into several smaller ones, but here the aprons are divided and the taxiway passes between them. In other words. If one huge and complete apron is drawn then the taxiway will pass through the cross. That's not here.
2) Taxilane / Parking_posirion , using Parking_position is universal (simpler), can be a point and a line.
Additionally, the help for Parking_positioin states "draw a line from the taxiway to the stopping point and mark Pakking_position". The description of Taxilane in the help is also a bit confusing because it also refers to the runway.
