[gdal-dev] Interlis driver does not polygonize anymore

[Stefan Ziegler]

I think my answer is still on hold because of the attachements. Now the
answer w/o attachements:

Ok, the autotest example runs smoothly. It seems a problem with the order
of the relation attribute "Entstehung" in the table
Bodenbedeckung__BoFlaeche in my data (link see below). It is added as the
last attribute in the table but actually it's the second one (after TID).

I remember that the order of these relation attributes are a bit nasty to
handle. Pirmin, can you confirm this behaviour/bug? I guess this was
introduced with the change from ili (java) to imd?
