  * 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.
