A "Unicode set" in this context means "a set of code points". This is discussed in section 1.2:
-- This is done by providing syntax for sets of characters based on the Unicode character properties, and allowing them to be mixed with lists and ranges of individual code points. -- More generally, there is no term "Unicode set" defined, although is it referred to in places such as RL1.3 as a shorthand. It merely means "the set of all code points selected" (by whatever selection, subtraction, intersection, or differencing has been applied beginning from the Universal Character Set as a whole). Or at least this is how I have already read it.
