Well, this seem to go back to the question of whether "husband" should
be treated as a class - a subclass of males or as a relationship (object
property).
In this example husband is treated as a relationship between 2 concepts
(classes) - male and female. Are you saying that it would be better to
have "husband" as a class?

Sorry to be picky, but wouldn't this be in all countries (a "husband" is
never female)? :)
