The situation at night is a bit clearer:
So basically, the CTR transforms into an RMZ at and below 1.500ft AMSL and above it is swallowed by the TMA. Dutch Mil is the controlling unit of the Maastricht TMA 1 outside the Tower's operating hours.
I was also expecting something along the lines of "The TMA is this except the airspace contained in the CTR", either in the definition of the TMA itself, or as a general rule, but I guess it's considered obvious!
The truth of the matter is that there is a huge variation of arrangements within and between various States. You really need to look at each location in the relevant AIP on a case by case basis to work out airspace classifications/configurations/which unit manages it/and when.
