Doesn't work app.directive('svg')

[59naga]

var app=angular.module('myApp',['jaggy']);
app.directive('svg',function(){
  return {
    restrict:'E',
    link:function(){
      console.log('This not edge...');
    },
  };
});

<img src="whatever.png" jaggy><!-- rendered <svg>-->

The above does not work.
