FWIW, my understanding of "basing on" matches Leif's above.

The idea with "basing on" CMS as I understand it is to avoid
starting over with analysis of the basic concepts and features
(cutting things out is fine) and was not to say "use ASN.1
encoding".

Maybe "basing on" wasn't a good term. Whatever.
