When modelling templates, a repeating element or cluster can be explicitly cloned and further constrained from the original archetype, like the way the “Atypical finding” cluster is cloned in this screenshot:
This doesn’t seem to be possible when making an archetype specialisation using Archetype Designer. Is this a limitation of the tool, or of the specs?
No opinions at all? This is highly unusual! 
Hi siljelb ,
yes you are right there is no “cloning” option when making the archetype but is there any difference between cloning and copying? I am able to copy and then after selectin the cluster parent I am able to paste the elements. One major difference I notice is that the nodeID is not a sequence of the original i.e 14.1.2 ,14.1.3 but rather a complete new at00xx.
Hi Rony,
The difference is as you point out; the node ID will be completely different. So it’s considered a completely new container instead of an instance of the initial repeatable container, and won’t be queryable as instances of that container.
It’s AD. Adl2 definitely supports this. So does Sign In with Auth0
In adl2 the model and syntax for specialised archetypes is the same as for templates. So it can’t make a difference regarding specialising repeating cluster nodes either.
