	// s.Elem() may return a nil, a Schema value, or a Resource value.
	//
	// The design of Elem() follows Terraform Plugin SDK directly. Case analysis:
	//
	// Case 1: s represents a compound type (s.Type() is one of TypeList, TypeSet or TypeMap), and s.Elem()
	// represents the element of this type as a Schema value. That is, if s ~ List[String] then s.Elem() ~ String.
	//
	// Case 2: s represents a single-nested Terraform block. Logically this is like s having an anonymous object
	// type such as s ~ {"x": Int, "y": String}. In this case s.Type() == TypeMap and s.Elem() is a Resource value.
	// This value is not a real Resource and only implements the Schema field to enable inspecting s.Elem().Schema()
	// to find out the names ("x", "y") and types (Int, String) of the block properties.
	//
	// Case 3: s represents a list or set-nested Terraform block. That is, s ~ List[{"x": Int, "y": String}]. In
	// this case s.Type() is one of TypeList, TypeSet, and s.Elem() is a Resource that encodes the object type
	// similarly to Case 2.
	//
	// Case 4: s.Elem() is nil and s.Type() is a scalar type (none of TypeList, TypeSet, TypeMap).
	//
	// Case 5: s.Elem() is nil but s.Type() is one of TypeList, TypeSet, TypeMap. The element type is unknown.
	//
	// This encoding cannot support map-nested blocks or object types as it would introduce confusion with Case 2,
	// because Map[String, {"x": Int}] and {"x": Int} both have s.Type() = TypeMap and s.Elem() being a Resource.
	// Following the Terraform design, only set and list-nested blocks are supported.
	//
