In section 8.14.2 DeviceMetric resource is listed as device related resource, but the Device resource does not reference it. Also, looking at the Device resource structure, not all referenced resource are menitoned in section 8.14.2.

Suggest correcting and making this list in 8.14.2 complete. In case the goal of this section is different, please clarify (for example why DeviceMetric and not DeviceUsage is mentioned).
