Hi,

Documentation of the WFS driver and config options
http://www.gdal.org/drv_wfs.html
https://trac.osgeo.org/gdal/wiki/ConfigOptions do not mention that
GML_EXPOSE_GML_ID and GML_EXPOSE_FID are supported. Compare with another
configuration option: 

GML_INVERT_AXIS_ORDER_IF_LAT_LONG
GML driver specific. Added in GDAL/OGR 1.8.0. See ​GML driver documentation.
Also impacts WFS driver behaviour. 

I think that you are trying to use a non-existing feature. I don't know why
it could not be supported, though. Wait for a confirmation from some
developer and consider making a feature request. For me ogrinfo from the
data I captured from WFS and saved into GML with default parameters looks
indeed confusing:

OGRFeature(lv_editable_points):12
  fid (String) = lv_editable_points.12
  gml_id (String) = editable_points.13
  string (String) = kkk
....
