I've tried that, it doesn't throw an error so far but it seems to be empty.
I've took a look at some groundnet xmls and EDDF has definitely taxiways
with names assigned. So I use that for testing.

my test code:
```
var apt = airportinfo("EDDF");
foreach( var taxi; apt.taxiways)
{
	print(taxi.id);
}
```
This doesn't print anything.


(there it seems a bit in-consequently written... rwy code doesn't work
for twys and the other way around)

I've tried that too (on EDDF again) with the code example from the wiki:
```
var path = "/demo";
io.read_airport_properties("EDDF", "groundnet", path);
props.dump(props.globals.getNode(path));
```

This just creates an empty prop.

I've been running this on 2018.1 build with the d&c script with -s.

What I'd need is a list of taxiways containing the coordinates, the
heading and the id.
