Joe,

Could you expand more on the expected use of the "feature" string?

   48     /**
   49      * Name of the preview feature the annotated API is associated
   50      * with.
   51      */
   52     String feature() default "";


Could you maybe give some examples of what feature strings might be, and 
how you might expect the string to be used, especially in a non-English 
locale? Would you expect to see any enforcement of the set of permitted 
strings?
