 - `%0`, `%1`, etc - Formats the specified diagnostic argument based on its type.
 
-- `%select{a|b|c}0` - Chooses from a list of alternatives, separated by vertical bars, based on the value of the given argument. In this example, a value of 2 in diagnostic argument 0 would result in "c" being output.
+- `%select{a|b|c}0` - Chooses from a list of alternatives, separated by vertical bars, based on the value of the given argument. In this example, a value of 2 in diagnostic argument 0 would result in "c" being output. The argument to the %select may be an integer, enum, or StringRef. If it's a StringRef, the specifier acts as an emptiness check.
 
 - `%s0` - Produces an "s" if the given argument is anything other than 1, as meant for an English plural. This isn't particularly localizable without a more general `%plural` form, but most diagnostics try to avoid cases where a plural/singular distinction would be necessary in the first place.
