How does aacskeys determine the position of the device key in the tree? According to the spec (3.2.3) there is a path number associated with each device key which determines the path from the root to the position of the node. Without the position i wouldn't know which device key to choose and how to proceed from that node to the processing key. You see my point: that path number isn't stored in the ProcessingDeviceKeysSimple.txt file. I was aware of the fact that the source code already allows the use of device keys but there is just no way to store them other than hacking them into the source code. All keys should generally be stored in a separate file.
