PINT Extensions - per [RFC2848] There are three kinds of identifier used in PINT extensions that SHOULD be registered with IANA, if a new value is specified. These are: * Media Format sub-types, as described in section 3.4.2 of [RFC2848] * Private Attributes as mentioned in section 3.4.3 of [RFC2848] * Private Phone Context values, as described in section 3.4.3.1 of [RFC2848] It should be noted that private Address Types (in section 3.4.1) of [RFC2848] have been explicitly excluded from this process, as they must be in the form of an X-Token.
