Card Processing DSL

Чуваки а скажи есть какой DSL, типа COBOL на котором можно записывать карточные
банковские продукты для процессинговых систем, типа такого:

program [ name ]
grace-period [ days | formula ]
late-fee [ days | formula ]
turn-off [ limit [ days | formula ] ] [ message ]
cash-back [ beneficiary | type | invoice ]
rate [ formula ]
fee [ transaction | month | annual ]
bonus [ formula ]

Вот например как я вижу описание продукта

card M-PLA-CB UAH
    limit unknown
    grace-period first 100 days then 60 days
    penalty daily 100
            month add-rate 5%
    currency convert 1%
    rate month 4.9% of credit
    fee month 12 once on initial-payment
        month 3% of debt limit min 50 max debt
        month 1.2% of debt
        month 24
        status disabled 10
        transaction cashin  0
                    cashout pos ATMOSPHERA 0
                    cashout contry UA 5 + 1.5%
                                    _ 30 + 1%
                    wire target local 0
