sounds good. This discussion showed, that a record is more than a

I'm not sure if I understand the approach completely. The Header can
not be accessed as a CSVRecord, right? CSVRecords know the header
values through get(string). What happens if the format does not
support a header? UnsupportedOperationException?
If I got you right, we could use getHeaders() to know, which header
values are available.
Maybe it would be useful to have the record implement iterable as well.
