Passport includes all sort of foreign language support, I believe. Doesn't the Quark page detail the features of each?
Edit: Okay, this took the actual typing of the word "quark" in a browser address bar, and three mouse-clicks:
"QuarkXPress Passport is a complete, fully functioning version of QuarkXPress that includes additional features for multi-language publishing. QuarkXPress Passport contains dictionaries and hyphenation information for 11 languages."
I gotta hand it to ya, you get the award for NN Forums Laziest Web Researcher.
