After the provisioning request is accepted, the device may get different IP addresses, but the provisioning will still apply to the device that was identified during the request process. Note: Network Access Identifier is defined for future use and will not be supported with v0.1 of the API.
 
     * **Notification URL and token**:
-    Developers may provide a callback URL (`sink`) on which notifications about all status change events (eg. provisioning termination) can be received from the service provider. This is an optional parameter. The notification will be sent as a CloudEvent compliant message. If `sink` is included, it is RECOMMENDED for the client to provide as well the `sinkCredential` property to protect the notification enpoint. In the current version,`sinkCredential.credentialType` MUST be set to `ACCESSTOKEN` if provided.

         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.
