Cannot specify default NS instantiation level of InstantiateNsRequest and ChangeVnfFlavourData data types

On Note 5 of InstantiateNsRequest data type is stated that "[..] If none of the two parameters (nsInstantiationLevelId or targetNsScaleLevelInfo) are present, the default NS instantiation level as declared in the NSD shall be used." It is not clear where the default NS instantiation level attribute should be placed.

Same issue for ChangeVnfFlavourData data type.
