Unfortunately, AC 103.6 appears so far out of date and was created before class E airspace was invented.

Surface area of class E airspace designated for an airport existed, it just went by a much simpler name: "Control Zone"

I agree with Marty. Surface Area of class E airspace designated for an airport includes the class E extensions to class D airspace.
