Is this a PKCS#7 structure with the encapsulated content not being of type
data? Will the CMS routines work instead? Perhaps not because that's one area
of incompatibility between the two formats.

If you can use CMS then that uses an OCTET STRING to store the encoding of the
encapsulated content and makes no attempt to decode it.
