Hilton,

The KeyTransRecipientInfo syntax does not include a field to carry or
identify the originator's key management public key.  This is required for
key agreement algorithms such as D-H.

The recipient's cert indicates which flavor must be used.  If it is a key
transfer algorithm such as RSA, then the KeyTransRecipientInfo syntax is
used.  If it is a key agreement algorithm such as D-H, then the
KeyAgreeRecipientInfo syntax is used.
