+ * To skip automatic type detection the following prefixes may be used to
+ * enforce a specific type: ipv4:, ipv6:, rfc822:, email:, userfqdn:, fqdn:,
+ * dns:, asn1dn:, asn1gn: and keyid:. If a # follows the :, the remaining data
+ * is interpreted as hex encoded binary data for that ID, otherwise the raw
+ * string following the prefix is used as identity data, without conversion.
+ * To specify a non-standard ID type, the numerical type may be prefixed
+ * between curly backets, building a prefix. For instance the "{1}:" prefix
+ * defines an ID_IPV4_ADDR type.

  * This constructor never returns NULL. If it does not find a suitable
  * conversion function, it will copy the string to an ID_KEY_ID.
