Russ,

The problem is that the current CMSKEA draft includes two different usages
of id-keyExchangeAlgorithm each associated with different parameter
definitions.  As Jim pointed out, this is not a good situation since an OID
should always be associated with a single parameter definition.

The proposed solution (which Jim has agreed to) will define a unique OID
(i.e. id-kEAKeyEncryptionAlgorithm) to be used in the
KeyAgreementRecipientInfo keyEncryptionAlgorithm field.  The parameters
definition for the new OID will be KeyWrapAlgorithm (using id-fortezzaWrap80
OID).
