Very interesting thread, with many good points. I hope we keep it simple (quick) here in the US. When vectoring for the approach its a simple, PTAC.. Position (in relation to an approach fix) Turn (degree intercept determined by a/c type), Altitude (to maintain until established), Clearance for the approach. While not being vectored a simple issuance of an altititude to maintain until the approach fix then the clearance for the approach (mainly used in the ARTCC enviroment). Lastly if an a/c has reported on say the localizer we just give the clearance for approach.
Again a very interesting thread, it's amazing of all the different ways/standards to reach the same results..safety.
