public class MapUntypedContains
extends SystemFunction

Implementation of an internal function map:untyped-contains(Map, key) => boolean, which is like map:contains except that if the supplied key is untyped atomic, it is converted to all the possible types present in the map and returns true if the key after conversion is present. In addition, if the supplied key is NaN then the result is always false.
