justification Justification Fill field data side "RIGHT"
justification_element str Data for fill field data side "0"
justification_length int Fill field data side up to length 16
field_type_validators LogicalValidators Validate field on some dictionary includement ["some", "values"]

Logical validators

This group of complex validations checks calculated, logical values, such as the Luhn algorithm, present/past tense, inclusion of a field value in a dictionary, etc
