Dexron II and III are these Standards?

My older car, a 1999 Mazda calls for Dexron II in the power steering system. I see Dexron III is what is now offered. Is Dexron III a replacement for II, i.e., an improvement over II?

Another question, the on-hand ATF I have is Shell Dexron III, so it must not be too new, I've had the bottle for longer than I can remember. To the question, going to Walmart (yes I know they are not THE auto parts store) I find several brands of ATF, including two from Castrol, a brand I trust. None display Dexron III, albeit the one of the Castrol bottles says in details that the fluid meets Decron III and Micor...(something, forget). This leads me to conclude Dexron is a "standards" not a brand-name, correct? Then, given my owners manual calls for Dexron II or III I assume I should not buy anything that is silent about its compliance with Dexron "standards".
