Skip nested forms validation with AngularJS

Question

How can I skip validation of nested forms with AngularJS? I have to make an outer form valid even when its child form is invalid.

In the example below outer form sh

Also inspired by mbernath, I found a simpler solution. It consists of creating a dummy form-like directive only for isolation. The directive stops propagation from nested elements to outer form but it doesn't have any form functionality. You can nest ngForms inside and have them fully functional.

angular.directive('formIsolator', function () {

            return {
                name: 'form',
                restrict: 'EAC',
                controller: function() {
                    this.$addControl = angular.noop;
                    this.$$renameControl = function(control, name) {
                        control.$name = name;
                    };
                    this.$removeControl = angular.noop;
                    this.$setValidity = angular.noop;
                    this.$setDirty = angular.noop;
                    this.$setPristine = angular.noop;
                    this.$setSubmitted = angular.noop;
                }
            };
        })

The way is to specify the name of controller in directive definition (name: 'form'). This property isn't documented, but is used for creating ngForm directive in angular source.
