The original signing-time attribute defined in [CMS] has the same semantics
as the updated signing-time attribute specified in this
document. Therefore, only one of these attributes SHOULD be present in the
signedAttrs of a SignerInfo object or in the authAttrs of an
AuthenticatedData object. However, if both of these attributes are
present, they MUST provide the same date and time.

I think it is up to *you* to explain why there is a SHOULD, a MUST
or whatever addressing the situation of two semantically equivalent
occurences of a time value, whilst in the definition of
signingTime there are several MUSTs ensuring only one.
