I also agree with John Pawling, that any extension must be controlled and

As per Peter's comment, control of the choice can be achieved by the normal
RFC process.  Also, if more control is required on S/MIME for interoperability
reasons, the S/MIME specification (not the CMS spec) could prohibit the
expansion of the choice unless a new version number is agreed.
This sounds like a good way to handle it, that way MSG can profile the stuff
specifically required for S/MIME leaving CMS able to be extended to handle
things which aren't necessarily useful for S/MIME, but are useful for other
applications (things like protection of stored data, of which PKCS #15 is a
prime example).
