From my reading of the referenced page it looks like the xml file is used to define storage areas -- like files -- in the external EEPROM, but it doesn't address initializing the contents prior to running your program.
You could implement a message to send and store your key. I don't know if there is any erase of external EEPROM done when a device is programmed, so the contents _might_ persist across new downloads and thus you would only have to do the message thing once. Another possibility is that there is a small internal EEPROM area on each controller. In T1 one accessed this using the InternalFlashC component -- which has probably changed names in T2. This memory _is_ erased but can be initialized at download time. I don't think TOS has implemented any method to do this so you would have to dig through the controller and download utilities to figure out how to do it.
