## Why it fails

- The account in `cac:PayeeFinancialAccount/cbc:ID` for a SEPA credit transfer (code `58`) is not a valid IBAN: a typo, a missing digit, or an account number without the country and check digits.
- The IBAN contains characters other than letters, digits and spaces.

## How to fix it

- Give the full IBAN, with or without spaces. Its two check digits are verified, so a single wrong digit is caught; copy it from the bank statement rather than retyping it.
