Thanks gentlemen (women?) for all your comments. I'm going to see if I can write a summary tomorrow and maybe put it up on wikipedia or something. I cannot believe I'm the only PPL who doesn't understand this... Particularly the fact that I learned things the CAA way (Responsible Person etc.), thinking that that was, in fact, the JAA/European way, and then coming back into a totally different environment had me puzzled. Who was the norm, who was the exception? This has made things a lot clearer.
