Hi, Richard-

Thanks for your helpful and detailed comments, and sorry for the delayed 
response.  I believe I have addressed all these comments in the latest 
editor's draft of the spec [1], using your suggested wording (thanks 
especially for that).  Please let me know if I've messed something up.

I look forward to any further improvements you or the other i18n folks 
have for the spec.
