OK:
All values that correspond to the same logical field are exactly equal.
OK_PUNCTUATION_UPPER_CASE_CLEANED:
All values that correspond to the same logical field are equal after punctuation is removed and all characters are converted to upper case.
OK_DEBURRED:
All values that correspond to the same logical field are equal after punctuation is removed, all characters are converted to upper case and diacritics are replaced with their base characters.
OK_DEBURRED_EXTENDED:
Same as OK_DEBURRED but allows replacing diacritics not only with their base characters but also with some more complex combinations. E.g., according to ICAO 9303 MRZ standard Ü can be replaced with U or UE or UXX.
OK_TRUNCATED:
In addition to OK_DEBURRED_EXTENDED, allows one string to be a prefix of another string. Correctly works with complex diacritics replacements. In particular, if one string is MUEL and another is MÜLLER, then they are considered equal up to truncation.
INCONSISTENT:
The values that correspond to the same logical field are inconsistent.
The status of the consistency verification.
