Is MLS (Multiple Language Support) available out of the box or does it have an additional cost?

Quick question, we're implementing Oracle Fusion for a client and the discussion of foreign language invoices came up.  I understand MLS can do this, but am trying to determine if there's an additional cost beyond the added setup and admin efforts.

I realize this is the EBS group, so let me know if there's a better group and i'll repost.  I couldn't find anything that looked right.
