Also notice that the text mentions BASE-64 only in relation to
EnvelopedData (OriginatorInfo) and NOT in relation to SignedData,
although both EnvelopedData and SignedData may carry certificates.

Therefore the use of BASE-64, as specified by the current normative
text, only applies to the certificates included in EnvelopedData and not
to those included in SignedData, which are probably more common.  The
latter are encoded in hex.
