+    In this example we test the following cases :
+    <ul>
+      <li>Different values to create a literal with :
+        <ul>
+          <li>simple value : "${name}"</li>
+          <li>more complex value : "name: ${name}, age: ${age}, address: ${somewhere}, status: ${status}"</li>  
+        </ul>
+      </li>
+      <li>Different features :
+        <ul>
+          <li>one single attribute</li>
+          <li>4 attributes</li>
+          <li>9 attributes</li>
+        </ul>
+      </li>
+    </ul>
+    
+    Each test is made with a 1000 cycles loop.
