I have A7 commercial

In the manual I came across c_content which notes that it can only be used with, I quote:

"Works only with BSP levels and the AABB collision system."

Ok all fine there but I noticed that in the manual's collision engine description it says:

"In A7, BSP trees and the AABB collision system are only supported by the Pro Edition."

Hmm oh well. Yet I did use c_content anyway and it works with A7 Com. Have I misunderstood the manual?
