+        This experimental sample demonstrates the use of XMLHttpRequest to update
+        fields without refreshing the page. It is currently broken: the form
+        cannot be successfully submitted, as the form model does not contain the
+        values of the type and model selection lists. After selecting a value in
+        the "model" field, the "type" and "model" fields are reset to their initial
+        values, instead of submitting the form. See also bugzilla 34077.
