X-Life with X-Plane 11.50 airport crash workaround

I found a way to edit most airports (in fact, worked 100% on all airports I tried) where X-Life airport editor crashes.

I created a "standard" .xlf that I rename with the airport name (ex. UUYY.xlf) and edit file with a text editor.
The file includes :
- 4 nodes: node 0 for threshold 1, node 1 for reverse threshold (threshold 2), node 3 for runway vacated spot, node 4 for parking stand.
- 3 edges: edge 0 in for the runway and links node 0 and node 1, edge 1 links node 0 and node 3 for the hold area with 2,0,1 parameters (see attached file), edge 2 is a taxiway which links node 2 and node 3 with 2,0,0 parameters.
- 1 parking stand on node 3, i.e. same geo-coordinates.
- 2 runways: repeats QFU and coordinates of node 0 and node 1. WARNING: do not mix-up thresholds!

Replace all "<BLABLABLA...>" by appropriate values. Example :
- Runway thresholds: 12 and 30 (reverse)
- Geo-coordinates: 67.444885

WARNINGS:
1 - Make sure runway name (ex. "12/30") is consistent with the 2 runways: 12 and 30.
2 - All coordinates are extracted from Google Earth configured in decimal mode (not degrees, minutes, seconds of angles).
3 - Beware that coordinates are in NORTH and EAST, so NORTH and EAST are positive decimal numbers and SOUTH or WEST are negative numbers.
4 - Always download and install the gateway.x-plane scenery into X-Plane before start. For a reason I do not understand, the default X-Plane scenery usually will lead to X-Life airport (and X-Plane) crash.

NOTE: don't bother with taxiway nodes defined on the grass or in the forest instead of concrete. Once the airport editor is loaded, you will be able to change everything.
