Ah, that's where I made my mistake - thinking that it's controlled
airspace (as in Class B).

So here's a followup question: We know the TRSA space coexists with the
class E airspace. Does it also coexist with the class D airspace "in" the
TRSA airspace? Or are TRSA and class D mutually exclusive?

Does the answer to this question make any practical difference?
