How to use `replace` of directive definition?

In this document: http://docs.angularjs.org/guide/directive , it says that there is a replace configuration for directives:

template - replace the current element with the contents of the HTML. The replacement process migrates all of the attributes / classes from the old element to the new one. See the Creating Components section below for more information.

javascript code

app.directive('myd1', function(){
  return {
    template: '<span>directive template1</span>',
    replace: true
  }
});

app.directive('myd2', function(){
  return {
    template: '<span>directive template2</span>',
    replace: false
  }
});

html code

<div myd1>
  original content should be replaced
</div>
<div myd2>
  original content should NOT be replaced
</div>

But the final page is looking like:

directive template1
directive template2

It seems the replace doesn't work. Do I miss anything?

Replace [True | False (default)]

Dependency:

You are getting confused with transclude: true, which would append the inner content.

replace: true means that the content of the directive template will replace the element that the directive is declared on, in this case the <div myd1> tag.

http://plnkr.co/edit/k9qSx15fhSZRMwgAIMP4?p=preview

For example without replace:true

<div myd1><span class="replaced" myd1="">directive template1</span></div>

and with replace:true

<span class="replaced" myd1="">directive template1</span>

As you can see in the latter example, the div tag is indeed replaced.

As the documentation states, 'replace' determines whether the current element is replaced by the directive. The other option is whether it is just added to as a child basically. If you look at the source of your plnkr, notice that for the second directive where replace is false that the div tag is still there. For the first directive it is not.

First result:

<span myd1="">directive template1</span>

Second result:

<div myd2=""><span>directive template2</span></div>
