Frank,
If we "connect this to the -select option of ogr2ogr" as you suggest, it
would probably be helpful to specify fields by name rather than by number in
order to accommodate the OS MasterMap data.

At the risk of repeating myself from another thread, the OS MasterMap
Topology Layer vector data has identical field names (for any given layer)
in all data chunks, but the field numbers are different in different chunks.
Just to complicate matters, some fields are entirely missing in some data
chunks too! :-(
Jez,
With all due respect:
o The -select already uses names, which can be internally converted
to field indexes within ogr2ogr. Users don't ever give numbers for
fields.
o Within *one* layer the fields are consistent. I don't think the
issue with different field lists and ordering between gml files
has any real bearing on the "set desired fields" RFC.
Best regards,
