Martin,
When I convert Ordnance Survey MasterMap GML to ESRI Shapefiles using ogr2ogr, I'm getting different field numbers for the same field name in different GML chunk files. Apologies if I have the wrong end of the stick, but wouldn't your proposed interface therefore require me to invoke ogr2ogr differently for each different GML chunk file, in order to accommodate the different field ordering? Assuming I'm right, wouldn't it be more useable for the interface to use field names rather than numbers?
