    The DelimitedIF forwards the returned `null` to the DataSourceTask where it is ignored.
Hence, there is no checking for input correctness. If the CsvIF was configured with lenient

> The current skipFirstLine is limited. Skipping arbitrary lines that start with a certain
character would be much more flexible while still easy to implement.
