As we defined in new certificate format (http://gerrit.named-data.net/#/c/2101/, http://redmine.named-data.net/issues/2861), there will be an non-critical extension AdditionalDescription. As defined in the certificate spec:
> AdditionalDescription is a non-critical extension that provides additional
> information about the certificate. The information is expressed as a set of
> key-value pairs. Both key and value are UTF-8 strings, e.g.,
> ("Organization", "UCLA"). The issuer of a certificate can specify arbitrary
> key-value pair to provide additional description about the certificate.
