It is true that all ConfD examples have config false on the topmost container, but by no means this needs to be the case. For instance, the basic stats example looks like

  container arpentries {
    config false;
    tailf:callpoint arpe;
    list arpe {
      ...
    }
  }

But since there are no other nodes under arpentries, the example would work exactly the same if the two statements were moved into the arpe list like this:

  container arpentries {
    list arpe {
      config false;
      tailf:callpoint arpe;
      ...
    }
  }

Nothing needs to be changed in the example and it still works.

In your situation you just indicate that lock-state is a non-config leaf and declare your callpoint that you implement in your data provider code; the same holds for other leaves or the list sources. So the part of your data model can look like this:

  container ptp-status {
    ...
    leaf lock-state {
      config false;
      tailf:callpoint my-callpoint;
    }
    ...
    list sources {
      config false;
      tailf:callpoint my-callpoint;
      ...
    }
  }
