I don’t think unique-stmt works for this case, see https://github.com/netmod-wg/yang-next/issues/74

[trying here before the “netmod” list]

YANG Doctors,

Assume data model:

  +—rw tenants
      +—rw tenant [key]
          +—rw  key        string
          +—rw admins
              +—rw admin [name]
                   +—rw name     string

The "admin" list’s key “name” ensures that the names are unique per tenant, but not globally.   Is it possible to place a “must” statement on the “tenants” container to ensure globally-unique admin names?

Can anyone offer syntax to do so?

Isn't this a use-case for unique-stmt?

   list tenant {
       unique "admins/admin/name";
       ...
   }


Kent
