title: Significance of @ in AEM slightly
body: <p>Why we use @ symbol in AEM slightly code. What is the significance of @?</p>
  <p>For example:</p>
  <pre><code>&lt;section data-sly-resource=&quot;${'./path' @ resourceType='my/resource/type'}&quot;&gt;&lt;/section&gt; 
  </code></pre>
  <p>In above code why @ resourceType is used?</p>
