+                        <p>In order to re-create relationships between
+                        different records, you should use the unique
+                        identifier from the original application and
+                        map it to the <abbr title="External ID">ID</abbr>
+                        column in OpenERP. When you
+                        import an other record that links to the first
+                        one, use <abbr title="XXX/External ID">XXX/ID</abbr>
+                        to the original unique identifier.</p>
+                        <p>The <abbr title="External ID">ID</abbr>
+                        will also be used to update the original
+                        import if you need to re-import modified data
+                        later, it's thus good practice to specify it
+                        whenever possible</p>
