The "CMS" operations implement the "CMS" standard, formerly
known as PKCS#7, which is based entirely on the use of X.509
certificates.

Unless you can point out a clause in the "CMS" format RFCs
that allow use without X.509 certificates, there is no reason
why the "CMS" part of the OpenSSL library should be able to
any such thing.
