Thanks, I fixed that in the markdown.

I'm not clueful about this part, and generally quite fearful about parsing
this stuff.  Sure, it's easy in Ruby, but it's the constrained C code that
I'm concerned about, so I don't understand the tradeoffs here.

In other words: to not be PKCS7 compatible, but require CMS processing.

I think this is reasonable from a specification point of view, but there has
been pushback from people who have FIPS-140 libraries that they
have hard times getting updated.
