The notes do look old. The point that I think you are asking about is controlled airspace, the pointer is the bit about it being notified, this probably refers to 'notified for the purposes of schedule 8' which is a restriction on imc flight in some control zones. In the good old days before lettered airspace control zones had, if memory serves, an asterix by their designation if they were notified. These were what became class d probably but I cant remember to be honest. Some googling of schedule 8 weather provisions imc will give you the whole picture Im sure.
Hope this answers the point if not the detail of your question
