Does the type in this KVC validation method matter?

kvc

For example, in the docs a KVC-style validation method is implemented like this:

-(BOOL)validateAge:(id *)ioValue error:(NSError **)outError

They used id* as the type for ioValue. Since that's not part of the method signature, I wonder if it would hurt to do something like:

-(BOOL)validateAge:(NSNumber *)ioValue error:(NSError **)outError

Is this still fine with KVC?
