title: What are ISO languages?
body: <p>It's in fact 3 questions :</p>
  
  <ol>
  <li>What is required for a programming language to be certified "ISO" ?</li>
  <li>What does ISO certification guarantee about the language? Does other language can be the same?</li>
  <li>A list of ISO languages?</li>
  </ol>
  
  <p>(made community wiki - not sure about the organisation, maybe the first answer should be edited to have the full ISO languages list?)</p>
