/**
* A combination of an {@link Action} class and its corresponding instantiation wildcard, expressed as
- * an {@link InstanceIdentifier}. This glue is required because action interfaces are generated at the place of their
+ * an {@link InstanceIdentifier}. This means that {@code list}s are treated exactly as @{code container}s are, e.g.
+ * without a key value specification.
+ *
+ * <p>
+ * This glue is required because action interfaces are generated at the place of their
* definition, most importantly in {@code grouping} and we actually need to bind to a particular instantiation (e.g. a
* place where {@code uses} references that grouping).
