Artifact 7247e3cb9c9c3a32a867fa80caf6da2d6ff4c3f80c11ab2a941c8fcb1684d32b:

• File src/OFASN1IA5String.m — part of check-in [b1944fd052] at 2018-10-27 13:01:38 on branch trunk — Do not subclass OFASN1Value

  The reason for this is that OFASN1Value requires an initializer for DER
  encoding, however, it might be beneficial to create an ASN.1 type
  without providing DER encoding for it. (user: js, size: 2164) [annotate] [blame] [check-ins using]
