title: How can I represent an attribute which is a multidimensional array in UML?
body: <p>I am designing a new project in UML and I need a multidimensional array as attribute of one of my classes (Figure below)</p>
  
  <p><a href="https://i.stack.imgur.com/Je2DO.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Je2DO.png" alt="Example of class with multidimensional array as attribute"></a></p>
  
  <p>Right now I have put List of List to make everyone understand which are my purposes, but this is incorrect in standard UML. What should I do?</p>
  
  <p>Thank you for your help! </p>
