Detailed Description

If any of the fields in the otherFields list is not part of the input parameters, the field under validation must be present and not empty. For the other fields it will only be checked if they are not present in the input parameters, not their content.

Note
Unless validation is started with NoTrimming, whitespaces will be removed from the beginning and the end of the input value before validation. So, fields that only contain whitespaces will be treated as empty.
Return type
On success, ValidatorReturnType::value will contain a QString.
