I would agree and that was how I believed it to be until last year when E over D existed, however I was not able to find your reference to (AIP ENR 1.1.7). So under the E over D system you were bound by the lessor being E and now its C over D so its now D that you are concerned with. Yo can see why when I asked a few people about it I received many different ansers. The important point is the Lessor of the airspace types at the boundary is considered the one you are in.
Still cant find 1.1.7?? I will keep searching though....
