GtkBuilder still requires an <object> element for the internal
child, even if it has already been constructed.
</para>
+<para>
+A number of widgets have different places where a child can be
+added (e.g. tabs vs. page content in notebooks). This can be reflected
+in a UI definition by specifying the "type" attribute on a <child>
+The possible values for the "type" attribute are described in
+the sections describing the widget-specific portions of UI definitions.
