FIRDS has been updated to allow for new CFI codes.
Changes include allowing character 'X' in the 3rd attribute for forwards. Previously some forwards were limited to either C (CFD) or S (Spreadbet) due to a limitation in the ISO standard. To get around this, ESMA have allowed an 'X' to be populated in these circumstances.
E.g. For commodity forwards 'JT**X*' now allowed as ISO spec does not include 'JT**S*' (commodity spread bets)
