(Available since v1.1)
Requires that a value be a valid IBAN (International Bank Account Number) number. The annotation not only verifies the account checksum, but it also checks that the format of the account matches the official account format for that country. The set of patterns is stored in an external file called iban.properties, located in com\planetalia\dynject\validation\business. If a new country adopts the IBAN format or changes the internal structure of its accounts (unlikely), you should manually update this file.
