+<h3>The Model-Fragment Header</h3>
+
+<p>
+The Model-Fragment header is used to register a model fragment file as an extension to the application model, 
+similarly to extensions of <a href="../extension-points/org_eclipse_e4_workbench_model.html">org.eclipse.e4.workbench.model</a>.
+The EModel-Fragment header must use the following syntax:
+</p>
+
+<pre>
+Model-Fragment ::= filename;apply= ( 'always' | 'initial' | 'notexists' )
+</pre>
+
+
+The following is an example of the Model-Fragment header:
+</p>
+
+<pre>
+Model-Fragment: fragment.e4xmi;apply=always
+</pre>
+
+<p>
+  The <code>apply</code> attribute is optional and defaults to <code>always</code>. It can have the following values:
+  <ul>
+    <li><b>always</b>: each time the application started potentially replacing existing model elements and loosing information stored</li>
+    <li><b>initial</b>: only when coming from a none persistent state</li>
+    <li><b>notexists</b>: only if the given element does not exist already in the model</li>
+  </ul>
+</p>
+
