The schema version 3.1 is updated with a new currency code to a new version 3.2,
which is backward compatible with the previous version. Bank A created a report using schema
3.1. The report contains a version attribute 3.1. The report from Bank A will be validated with
the schema 3.2. Bank B created a report using schema 2.4, which is incompatible with the
current version 3.2. By checking the version attribute in the report, which is 2.4., the processing
application will identify that the report was created with incompatible version and Bank B will
be notified that it needs to update the schema.3
