'the empty string "" which denotes the native environment'
This is probably a case where you read the right thing from the docs if you 
know the answer anyway, but don't if you don't. Maybe you should propose a 
re-phrase of that (plus the other missing bits) that you suppose would have 
answered the question for you.

Ah, I thought the question was about the syntax (I read it in the context 
of you wanting to create your own locale).

Oh, I assumed anyone knew about that. Probably another candidate for adding 
"see also" references.
