Is there a potential conflict with CMS 12.3.1? That is:

   Any symmetric encryption algorithm that a CMS implementation includes
   as a content-encryption algorithm must also be included as a key-
   encryption algorithm.  

As I understand this this means that a CMS implementation using IDEA
must also include a means to wrap content encryption keys with IDEA.
This would require additional information and a new OID
id-alg-CMSIDEAwrap for example.
