Hi Dmitry
When testing your example I get "No mini-driver registered for 'AGS'.":
>gdal_translate -of PNG ags.xml ags_test.png --config CPL_DEBUG ON
ERROR 1: GDALWMS: No mini-driver registered for 'AGS'.
GDALOpen failed - 1
GDALWMS: No mini-driver registered for 'AGS'.
Do you know if this AGS mini-driver code is made publicly available i.e.
being pushed to the GDAL source/trunk?
Yours, Stefan
