+      <p>
+        In Lenya projects, the wrapper pattern (also known as adapter pattern) has proven
+        useful to simplify the handling of XML documents. A wrapper object provides
+        access to a certain object, in our case a Lenya document, to client objects. It can
+        be used to add a layer of abstraction. In our case we use the wrapper to abstract
+        from the XML content and provide the functionality of adding "knows" relations
+        between person documents.
