#  CmsOptions is a JSON string of advanced CMS/PKCS #7 signing and validation options.  The default
#  is an empty string, which selects normal behavior.  An empty JSON object {} is also valid.
mime.put_CmsOptions("{}")

#  UnwrapExtras controls whether UnwrapSecurity adds informative header fields describing the
#  security layers it removed.  The default is True.
mime.put_UnwrapExtras(True)

#  UncommonOptions is a semicolon-delimited option string for uncommon compatibility requirements.
#  Normal applications should leave it empty, and it should only be used when directed by support.
