title: Represent a dictionary within a dictionary
body: <p>I am creating UML diagrams that will represent C# code and I've reached somewhat of an impasse. I am currently representing a <code>Dictionary&lt;object, object&gt;</code> by using a qualified association, where the qualification is the key type and the class at the end of the association is the value type.</p>
  
  <p>Now I would like to represent a type in UML, like so: <code>Dictionary&lt;int, Dictionary&lt;object, object&gt;</code>. Is there any type of standard I can use to create a relationship that will accurately represent this relationship?</p>
