        The developer can choose to provide the below specified device

        identifiers:

        * `ipv4Address`

        * `ipv6Address`

        * `phoneNumber`

        * `networkAccessIdentifier`

        NOTE1: the MNO might support only a subset of these options.

        The API invoker can provide multiple identifiers to be compatible

        across different MNOs. In this case the identifiers MUST belong to

        the same device.

        NOTE2: for the Commonalities release v0.4, we are enforcing that the

        networkAccessIdentifier is only part of the schema for

        future-proofing, and CAMARA does not currently allow its use.

        After the CAMARA meta-release work is concluded and the relevant

        issues are resolved, its use will need to be explicitly documented

        in the guidelines.
