Q: File Adapter - enforcing file structure

Question

A simple question - if I have a BPEL process picking up a CSV file via File Adapter, how do I enforce the structure in the CSV file? e.g. if a record in the file is short a comma, I want that record to be fished out as erroneous.
From what I can tell after a few short test cases, if a record in the CSV file is short a field (i.e. missing a comma), the terminatedBy="," property in the XSD will case the adapter to parse the input file, including EOLs, until it reaches the next comma, typically spilling over into the next record. It does not recognize that short record as erroneous.
If this is unclear, please note and I'll try to further elaborate.
Thanks in advance -

Answer 1

Well, the terminatedBy for only the last field in the record is EOL. The other fields are terminatedBy a comma. Here's a sample XSD for the process in question -
