Hmm, that's an idea. 

What I'm wondering about first, though, is whether this feature -- one
of those, if you need it, you need it bad things -- can be understood
to be an implication or special case of 3.3 or 3.7. That would be nice
because it would mean not having to write another req or DO.

I think Yoshio mentioned something back in the early days of the WG
about being sensitive to i18n issues, which this feature request
does. (If anyone needs to hear a use case, I can provide one related
to task computing in multilingual environments.)

Best,
Kendall
