Eliot,
I agree that it probably should be a domain, for the reasons you describe. However, there are other languages where a phonetic "ruby" could be useful. I've seen the same kind of thing in Chinese texts (mostly in language learning aids), and I'm sure there are other uses.
So, I would suggest that any specification description not imply that usage is limited to Japanese.
Best Regards,
Richard
