You can see it in the draft "draft-ietf-ntp-using-nts-for-ntp-03". There it is mentioned e.g. in sect. 6.1.3.2. The idea is that NTS for NTP defines one additional extension field (see section IANA registration) and that all NTS-messages are using this extension field. The different NTS message types are distinguished by their respective OID (see the next version of the draft "draft-ietf-ntp-cms-for-nts-message"). This also is true for the MAC. Kristof please correct me if I'm wrong. The field type of the NTS extension field is not registered yet. This has to be done as soon as possible. This was also discussed with the NTF.
