Doubt about bit 028

[alexandrezanetti]

Hi, I could read in some place that the specification for this field 028 (x+n 8) uses 9 bytes and in other places 8 bytes.
Can you check which one is correct?

In the DFDL example I could read C0001500

In Wikipedia I could find some information like that:
x+n Numeric (amount) values, where the first byte is either 'C' to indicate a positive or Credit value, or 'D' to indicate a negative or Debit value, followed by the numeric value (using n digits)

@alexandrezanetti Thanks for raising this. You are correct that Wikipedia has fields 028-031 as x+n8 which would appear to be 9 characters, and the DFDL schema has length 8 characters. There is also field 097 which Wikipedia has as x+n16 and the DFDL schema has length 16 characters. I will need to investigate why these differences exist.

@alexandrezanetti I suspect that the definition of the fields as x+n 8 was interpreted as (x+n) 8 instead of the x+(n 8). The latter is correct. Please feel free to fork the repo and create a PR to correct this. I think it affects the 1987 xsd fields 028/029/030/031/097, both packed and unpacked versions, and the associated test data will need to be updated to match. I don't think 1993 is affected.
