[gdal-dev] Missing geometry type when using ogr2ogr to write FileGDB

[Stefan Keller]

Hi Even

You're right about the parantheses of URLs with & in the shell.

Yes that's it.
To be specific, every feature/object/instance has a gml:Box and a
gml:Polygon (see below).
That's a weird output from this ArcGIS server stuff and an incomplete
response of DescribeFeatureType.

Yours, Stefan
