and add "label" element support.

@@ -597,6 +597,13 @@ Building an XRC for wxAuiToolBar is quite similar to wxToolBar.
 The only significant differences are:
 @li the use of the class name wxAuiToolBar
 @li the styles supported are the ones described in the wxAuiToolBar class definition
+@li the 'space' pseudo-class has two optional, mutually exclusive,
+integer properties: 'proportion' and 'width'. If 'width' is specified, a space
+is added using wxAuiToolBar::AddSpacer(); if 'proportion', the value is used in
+wxAuiToolBar::AddStretchSpacer(). If neither are provided, the default is a
+stretch-spacer with a proportion of 1.
+@li there is an additional pseudo-class, 'label', that has a string property.
+See wxAuiToolBar::AddLabel().
 
 Refer to the section @ref xrc_wxtoolbar for more details.
