I currently work on a client side validator base on server side rules and I think somethink can be enhance in FormError.

At the moment, if a FormError is throw from the validator, there is not way to know from which field/form the error come from (to use it on the client side for example).

I think it is a good idea to add the id (or the path) of the field/form where come from the FormError.

What do you think about it?
