Artifact d10f7216afe18b30b0c16ab5cfd5d65b4606450da25881a19913f5b6610c8d00:

• File src/OFASN1Boolean.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: 2104) [annotate] [blame] [check-ins using]
