However, the idea is: things that are common for both UAC1 and UAC2 are prefixed with UAC_, and only those things that are special get a number suffix. Which is the case in the block you quoted above. (This perticular detail is really the greatest unnecessary confusion in the UAC2 spec, btw. They just drop one enumeration value and shuffled two others around for no obvious reason. Now we have to live with that.)
