> event.email = e-mail

I am not sure what you want to achieve? Maybe some example?
You can always use a different key i.e. validation.error.email.required and then
validation.error.email.required = The field e-mail is required!
What you presented is the situation when you want to use exactly the
same validator for many fields without specifying key or with the same
key - it simplifies but isn't flexible ;-)
