Comment 4 for bug 778668

Although James could not validate the solution I suggested, I privately received the account number that he tried to validate and my suggestion does seem to do the trick.

Pieter, note that your modification to the Italian BBAN format in http://bazaar.launchpad.net/~pieterj/account-banking/5.0/revision/71#account_banking/sepa/iban.py is different from my suggestion and still gives the following error validating Italian IBANs:

account_banking/sepa/iban.py", line 131, in __extract__
    result += value[i+4]
IndexError: string index out of range

The reason for this is that the branch number is still 1 character too long.
