Yes, as far as I remember there were only one feature type per file, hence this
(non-fundamental) restriction in the code. I looked at bit at your sample and I
think you could just use the current code without changing it (well perhaps
increase the szHeader size). Add in the GML registry your feature types and make
them point to the same .gfs file that define all the feature types ! The only
drawback is that you could have empty layers if not all feature types are found,
but that should work OK otherwise.
