Some ideas on this -drawn from Contsys but agree basically there is a difference between a Problem ‘header’ and the individual problems within it. Can be quite tricky .

@joostholslag - the need to express problems at different levels of granularity is definitely true but I think it might be a slightly different issue. It is one of the reasons why managing a universal problem list will be in my IMO very difficult.
