x1 = cuxna3 (set) is the collection of options/settings that can be chosen by user x2 = cuxna1 ~ galfi1 for purpose x3.

cuxna2 is deleted; galfi1 was raised from an event abstraction to a person agent; the third sumti slot of this word is not predictable from veljvo (but is inspired by galfi2). x3 is the interface feature which the choices modify; for example, x3 can be the sound amplitude ('loudness') feature/setting on a speaker and x1 is a set of values for that feature (according to some scale) which can be achieved by the speaker output.
