    • isValid

      public boolean isValid(String code)
      The code list provided with the ZUGFeRD standard only lists four codes: de, fr, en, and es. Obviously, there are more codes available (in ISO 639-1). We won't check the presence of a code in ISO 639-1, but we'll check if the code consists of two letters and if it's lowercase.

      isValid in class CodeValidation
      Parameters:
      code - the code to be tested
      Returns:
      true if the code has the correct format
