They would generally expect that starts-with($x, $x) returns true for
any string $x, however, which is also how XPath handles the issue (the
empty string is a substring of any string, so any string starts with
and ends with it). The analogous of [example~=""] does not match be-
cause the empty string is not a token so it cannot be in the token set.
