title: access property of child directives
body: <p>Is it possible to access properties of child directives ?</p>
  
  <p>Here in this example:</p>
  
  <pre><code>&lt;parent&gt;
     &lt;child [name] = "foo"&gt;&lt;/child&gt;
     &lt;child [name] = "bar"&gt;&lt;/child&gt;
  &lt;/parent&gt;
  </code></pre>
  
  <p>in <code>ParentComponent</code>, I would like to recuperate value <code>['foo','bar']</code>, that is the value and order of the propety name of <code>parent</code>'s child directives.</p>
  
  <p>Is that possible ?</p>
