title: How to bind content of tag into into directive's scope?
body: <p>Say I have a directive like such:</p>
  
  <pre><code>&lt;my-directive&gt;This is my entry!&lt;/my-directive&gt;
  </code></pre>
  
  <p>How can I bind the content of the element into my directive's scope?</p>
  
  <pre><code>myApp.directive('myDirective', function () {
      return {
          scope : {
              entry : "" //what goes here to bind "This is my entry" to scope.entry?
          },
          restrict: "E",
          template: "&lt;textarea&gt;{{entry}}&lt;/textarea&gt;"
          link: function (scope, elm, attr) {
          }
      };
  });
  </code></pre>
