Schema error on the maximum length of the IBAN, or a functional rejection by the fiduciary.
Cause
The Release 2027 schema had a maxLength that was too small (issue #135, accepted, pending release); IBANs with spaces or lower case fall outside the expectation.
Fix
Deliver the IBAN contiguous in upper case (NL: 18 positions) and use the schema of the release in which the correction is included.
