The call to CPLHTTPFetch() in the GML driver is to retrieve the XSD from the 
schemaLocation attribute. 
If the driver doesn't manage to retrieve the schema, then it guesses it, which 
explains why this still works despite the error.

Because this hasn't been yet implemented. Patch welcome. This would involve 
adding new open options to the GML driver and set them in the WFS driver.
