Only if you represent content-in-a-specific-language as a class, which would mean having a different class and different cardinality constraint for every language. Which probably wouldn't be workable. But in any case you need to add the qualifier "in any given conceptual scheme". That definitely makes expressing the cardinality constraint in OWL unworkable.
