Rear Derailleur questions....

what are the rules of the Rear Derailleur?

Does it determine the number of gears you have or is that done by the shifters themselves being that is where the cable is pulled? Im refering to indexed DT shfters or brifters.

for instance, can i use a 10 speed detrail. on a 8/9 speed cassette? I realize that i probably couldnt use a derail. that came of a 6 or 7 speed on a 8 or 9 speed rear cassette being that there probably isnt enough movement and it wasnt designed for it(or can i)?
