    This checker does not raise exceptions on undefined sw1 values, e.g.:
      - sw1 sw2
      - 63  any
      - 6F  any

    and on undefined sw2 values, e.g.:
      - sw1 sw2

    Use another checker in the error checking chain, e.g., the
    L{ISO7816_4_SW1ErrorChecker} or L{ISO7816_4ErrorChecker}, to raise
    exceptions on these undefined values.
