Phil:
SET uses PKCS#7 v1.6. S/MIME v2 uses PKCS#7 v1.5. CMS is derived from
PKCS#7 v1.5.
PKCS#7 v1.5 and v1.6 are quite different from an encoding point of view.

Jim has brought up a good point that since they use PKCS #7 for
Authenticode (I think) as well as potentially for other stuff, he
doesn't want to cart around code for both CMS and PKCS #7.

If I'm not mistaken, that will be necessary anyway. PKCS #7,
we were told when we used it in the design of SET, assumes
EXPLICIT tags, but I believe that S/MIME assumes IMPLICIT.
I haven't looked closely enough at the two and run test
cases, but I would expect that there are some differences.
But maybe not.
