+    Insert objects. Seperates groups of objects by meta-type by
+    drawing a rule between them::
-      <table border="1">
-        <tr tal:repeat="object objects">
-          <td><span tal:condition="repeat/object/first/meta_type"

+        <h2 tal:condition="repeat/object/first/meta_type"
+	    tal:content="object/meta_type">Meta Type</h2>
+        <p tal:content="object/getId">Object ID</p>
+        <hr tal:condition="repeat/object/last/meta_type" />
+      </div>
+    Note, the objects in the above example should already be sorted by
+    meta-type.

     When a path expression is evaluated, Zope attempts to traverse the

     If a traversal step fails, evaluation immediately proceeds to the next
     path.  If there are no further paths, an error results.
+    The expression in a series of paths seperated by vertical bars can
+    be any TALES expression. For example, 'request/name |
+    string:Anonymous Coward'. This is useful chiefly for providing
+    default values such as strings and numbers which are not
+    expressable as path expressions.
     If no path is given the result is *nothing*.
