> Referential constraints are currently limited to primitive properties, potentially nested within complex properties, which requires e.g. to "resolve" referential constraints between complex properties or single-valued navigation properties into one <ReferentialConstraint> element per primitive property of the complex property, and key property of the related entity type.
> An obvious generalization is to also allow complex properties, meaning that each member property has the same value, and as a consequence single-valued navigation properties, meaning that the dependent navigation property has the same target as the principal navigation property. This is just a short-hand notation for adding referential constraints on all leaf structural / key properties.
