NOTE 4: The NWDAF's Serving Area information is common to all its supported Analytics IDs.
NOTE 5: The Analytics IDs supported by the NWDAF may be associated with a Supported Analytics Delay i.e. the Analytics report can be generated with a time (including data collection delay and inference delay) in less than or equal to the Supported Analytics Delay.
NOTE 6: The determination of Supported Analytics Delay and how the NWDAF avoid updating its Supported Analytics Delay in NRF frequently is NWDAF implementation specific.
