How to write an angularjs directive that makes use of both scope and attributes and refer it thru compiled partial?

I want to write a directive which takes advantage of custom attributes, as follows:

<plant-stages
    title="Exploration<br/>du cycle de<br/>développement<br/>de la plante"
></plant-stages>

The controller is currently as follows:

app.directive('plantStages', function () {
    return {
        restrict: 'AE',
        templateUrl: 'corn.figure.plant.stages.html',
        link: function (scope, element, attrs) {
        scope.title = attrs.title;
        }
    };
});

The partial is as follows:

<figure class="cornStages">
    <div>
        <p>{{title}}</p>
    </div>
    <div ng-repeat="stage in stages">
        <div class="stage{{stage.stage}}"></div>
        <div>
            BBCH&nbsp;: {{stage.bbch}}<br/>
            {{stage.displayName}}
        </div>
    </div>
 </figure>

The partial makes use of some scope model variables. And {{title}} should support plain HTML injection out of the view which embeds it, hence should be compiled. I tried to support this but without success.

What modification should I make to have the HTML compiled?

A bonus question: when I pass the attribute in, I create a dummy title variable in the scope that persists where it should only be local. How would one make changes to handle this?

If you want to wrap HTML in your custom directive take a look at the transclude option (see docs):

module.directive('myDirective', function() {
  return {
    restrict: 'E',
    transclude: true,
    template: '<div ng-transclude></div>'
  };
});

This enables you to place HTML within the directive tag which can be used in the template:

<div ng-controller="Controller">
  <my-directive>
    <h1>Test</h1>
  </my-directive>
</div>

In case you really want to pass HTML via an attribute use ng-bind-html. This requires the ngSanitize module:

module.directive('myDirective', function () {
  return {
    restrict: 'E',
    template: '<div ng-bind-html="title"></div>',
        scope: {
            title:'@'
        }
    };
});

I added this to your fiddle.
