Field Device Configuration .json sample missing Point objects for extension points

[GCoxCasey]

The example 'Filed Configuration.json' file in this repo contains two extension points as shown below in JSON.
https://github.com/LucidProtocol/Lucid-Specification/blob/master/Field%20Device%20Configuration.json

"extPoint": [
    {
      "parent": 1,
      "parentType": "ai",
      "num": 1,
      "name": "pump 1.Flow Average",
      "className": "Water.Pumps.ACME 245M",
      "type": "Mean",
      "resetPeriod": 86400000,
      "resetOffset": 0,
      "reportPeriod": 900000,
      "scale": 1.0,
      "units": "litres"
    },
    {
      "parent": 1,
      "parentType": "bi",
      "num": 2,
      "name": "pump 1.Run Time",
      "className": "Water.Pumps.ACME 245M",
      "type": "Run Time",
      "resetPeriod": 86400000,
      "resetOffset": 0,
      "reportPeriod": 900000,
      "scale": 1.0,
      "state": 1,
      "units": "s"
    }
  ],

But the Point section earlier in the same file does not show entries for the two extension points:

"point": [
    {
      "parent": 1,
      "num": 1,
      "type": "ai",
      "name": "pump 1.Flow",
      "className": "Water.Pumps.Acme 245M",
      "scan": true,
      "canOverride": true,
      "logRate": 900000,
      "logOffset": 0
    },
    {
      "parent": 1,
      "num": 1,
      "type": "ao",
      "name": "pump 1.Demand",
      "className": "Water.Pumps.Acme 245M",
      "scan": true,
      "canOverride": true,
      "logRate": 900000,
      "logOffset": 0,
      "whenRestart": 2
    },
    {
      "parent": 1,
      "num": 1,
      "type": "bi",
      "name": "pump 1.Status",
      "className": "Water.Pumps.Acme 245M",
      "scan": true,
      "canOverride": true,
      "logRate": 3600000,
      "logOffset": 0
    },
    {
      "parent": 1,
      "num": 1,
      "type": "c",
      "name": "pump 1.Starts",
      "className": "Water.Pumps.Acme 245M",
      "scan": true,
      "canOverride": true,
      "logRate": 3600000,
      "logOffset": 0
    },
    {
      "parent": 2,
      "num": 1,
      "name": "pump 1.Flow Filtered",
      "className": "Water.Pumps.ACME 245M",
      "type": "ai",
      "units": "litres",
      "canOverride": true,
      "scanRate": 900000,
      "scanOffset": 0,
      "calcCode": [
        34,
        31,
        10, 0, 1,
        120,
        1, 2
      ]
    },
    {
      "parent": 2,
      "num": 2,
      "name": "pump 1.Status point quality",
      "className": "Water.Pumps.ACME 245M",
      "type": "bi",
      "canOverride": false,
      "calcOnChange": true,
      "calcCode": [
        11, 1, 1, 1
      ]
    }
  ],

We would expect two extra Point entries with type "x" for the two extension points.
"num": 1, "type": "x",
"num": 2, "type": "x",

UPDATE

Looking at this in more detail, we can see another possible explanation her, maybe the diagram is incorrect (rather than the configuration sample) and Extension Points do not include a Point object.

The reason we are thinking this are:

• Some of the fields from Point class are included directly in the ExtPoint class: parent, num, name,className.
• But not ALL of the Point fields are included, so this may explain why the an entire Point object is not included for an Extension Point: for example: scan,canOverride, logRate, logOffset.

Is this understanding correct?
