use of inherited attributes and "struct" in a c++ subclass

Question

how do I use a superclass "Struct" in the subclass. I usually use attributes:

   using superclass<T>::Attribute;

But for a "Struct" with internal methods I do not know how you can do. However the superclass "struct" is declared protected as its attributes.

In the Superclass:

protected:

  struct Node{

    Data Elements;
    struct Node* Nxt;

    methods......

  }

I tried with:

using Superclass<T>::Node; and using Superclass<T>::struct Node;

but he gives me this mistake:

error: dependent using declaration resolved to type without 'typename'
  using List<Data>::Node;
