+member more precisely. Names represent elements and <text> and
+<cdata> represent plain text and CDATA, respectively. Edges point
+from parent to child. Unlabeled edges indicate that the child appears
+exactly once; edges labeled with *, zero or more times; edges labeled
+with ?, zero or one times. Where possible, child elements are shown
+in the order they actually appear within a parent element.
