You can tell which one from the Version INTEGER. However this was
mentioned before. The suggestion then was:

RecipientInfo ::= CHOICE {
  ktri KeyTransRecipientInfo,
  kari [1] KeyAgreeRecipientInfo,
  mlri [2] MailListRecipientInfo  }


I didn't mention it at the time but for the sake of minimalism I'd
suggest:

RecipientInfo ::= CHOICE {
  ktri KeyTransRecipientInfo,
  kari [0] KeyAgreeRecipientInfo,
  mlri [1] MailListRecipientInfo  }

The absence of tag on the KeyTransRecipientInfo is essential for
backwards compatability.
