title: How to make a two dimensional array in JSON Schema?
body: <p>How would you write the following two dimensional array in <a href="http://json-schema.org" rel="noreferrer">JSON schema</a>? The grid is fixed to 16*13. It contains completely empty rows or row with values like int(0-99) or an empty string.</p>
  
  <p>Here is an example of the array:</p>
  
  <pre><code>[  
    [],  
    [],  
    [],  
    [],  
    [],  
    [],  
    ['','','','',94,78,37,78,'','','',61,71],
    [42,82,53,62,65,47,65,77,26,93,69,69,51],
    [38,07,47,06,87,90,21,41,50,24,55,45,24],
    [55,69,'','','',83,04,90,34,88,99,28,71],
    [11,08,91,62,'','','','',36,53,57,76,65],
    [21,85,34,62,'','','','',76,67,20,77,85],
    [72,73,34,26,'','','','',37,22,49,89,26],
    [84,11,19,84,34,53,19,08,10,12,31,62,24],
    [36,94,43,27,71,30,86,96,37,45,19,60,50],
    [31,05,27,74,10,33,22,07,03,77,82,23,50]  
  ]
  </code></pre>
