The encrypted content is defined as:

Content              ::= CONTENT-TYPE TLV-LENGTH
                         EncryptedContent
EncryptedContent     ::= ENCRYPTED-CONTENT-TYPE TLV-LENGTH
                         EncryptionKeyLocator
                         EncryptionAlgorithm
                         EncryptedPayLoad
EncryptionKeyLocator ::= ENCRYPTION-KEY-LOCATOR-TYPE TLV-LENGTH
                         Name // name of encrypting key
EncryptionAlgorithm  ::= ENCRYPTION-ALOGRITHM-TYPE TLV-LENGTH
                         nonNegativeInteger // algorithm id
EncryptedPayLoad     ::= ENCRYPTED-PAYLOAD-TYPE TLV-LENGTH 
                         BYTE+

To implement the abstraction, please take the signature-info TLV implementation as an example.
