+            The option to list all intermediate calls between `departure` and `arrival`.
+
+            Intermediate calls are calls where no transhipment and no change of mode of transport takes place.
+
+            This structure allows intermediate non-transhipment calls to be grouped under a single leg, enabling consumers to present them as collapsed or expanded elements in the user interface, instead of treating each call as a separate leg.
+
+            The list only includes calls taking place **between** the `departure` and `arrival` of the current leg.
+
+            The order of the list is the order of visits from `departure` to `arrival`.
