Polar and me came to a conclusion that we need two separate versions of this unary transformation functions: integer-to-decimal, decimal-to-integer, round, abs, floor: restricting existing ones to require single<type> input argument format, not ne_sequence<> as in the current posted table, and one requiring sequence<type> as input - map version to be used for the use case of transofrming multiple values, to be used in set functions. Proposed new names are: map-round(sequence<xs:decimal> taking sequence<xs:decimal>), map-abs, map-floor, and so on. I will post updated table later today.
