    * A when constraint is a child of a case constraint. It provides a specific additional constraint that should be processed when 
   * the condition itself is true. 
   * 
   * So a case constraint on country, might have a when constraint with value='USA', and another with value='Canada'. Each of these
   * when constraints would define a constraint of their own that would only be processed when the country was USA, or when the country 
   * was Canada.
