Answer 1

If you need access to the form in your directive, you need to require it:

require: ['^form', 'ngModel'],
link: function($scope, elem, attrs, ctrls) {
   var form = ctrls[0];
   var ngModel = ctrls[1];

   if(form) {
     // use form to get whatever it is you care about.
     var whatever = form[otherProperty].$error.something;
   }
}

So given the above, you should be able to pass the form controller into your custom validation methods as a third argument, and handle whatever you need.

I hope this helps.
