Latest BAI2 lockbox seeded format

Summary:

We are requesting our bank to send lockbox data in seeded Oracle BAI2 format. As part of this, the bank has requested for latest seeded BAI2 format details for development from their end. Does anyone has latest documents on BAI2?

Also, Is it possible to capture additional information such as remitter's name in the standard BAI2 format? We couldn't locate any field that could be used to capture remitter information in standard format.
