We'd like a way to be able to decorate a setting in the settings view with an error message. Perhaps this is exposed as a service which can validate settings? Or each setting might have a hidden property associated with it that the settings page can display. So if I have a `dartlang.sdkLocation` config setting, the settings page listens to a 'hidden' `dartlang.sdkLocation._message` setting, and displays it in the page if a message exists."}}
