Bart,

Zero length attributes really means "length unknown" to OGR.  For
floats and integers it carries things around as a double or int.
Strings are carried around with arbitrary length.  Floats will be
formatted (by OGRFeature::GetAsString()) with "%.16g".

So, I don't think this means there is a problem.

Best regards,
