Section: 7 and 10.3

Original Text
-------------
Section 7 says

   OneAsymmetricKey ::= SEQUENCE {
      version Version,
      privateKeyAlgorithm PrivateKeyAlgorithmIdentifier,
      privateKey PrivateKey,
      attributes [0] IMPLICIT Attributes OPTIONAL,
      ...,
      [[2: publicKey [1] IMPLICIT PublicKey OPTIONAL ]],
      ...
   }

2nd example given in both section 7 and section 10.3:

   -----BEGIN PRIVATE KEY-----
   MHICAQEwBQYDK2VwBCIEINTuctv5E1hK1bbY8fdp+K06/nwoy/HU++CXqI9EdVhC
   oB8wHQYKKoZIhvcNAQkJFDEPDA1DdXJkbGUgQ2hhaXJzgSEAGb9ECWmEzf6FQbrB
   Z9w7lshQhqowtrbLDFw4rXAxZuE=
   -----END PRIVATE KEY------

ASN.1 dump of this private key in section 10.3:

   The same item dumped as ASN.1 yields:

     0 114: SEQUENCE {
     2   1:   INTEGER 1
     5   5:   SEQUENCE {
     7   3:     OBJECT IDENTIFIER '1 3 101 112'
          :     }
    12  34:   OCTET STRING, encapsulates {

          :         }
          :       }
          :     }

                 E1
          :   }


Corrected Text
--------------
Correct definition in section 7:

   OneAsymmetricKey ::= SEQUENCE {
     version                   Version,
     privateKeyAlgorithm       PrivateKeyAlgorithmIdentifier,
     privateKey                PrivateKey,
     attributes            [0] Attributes OPTIONAL,
     ...,
     [[2: publicKey        [1] PublicKey OPTIONAL ]],
     ...
   }

Example key in section 7 and 10.3:
