How to set different bundle for each Panel in SwiXML?

Hi,

How can I set different resource resource bundle for different panel in
SwiXML?
For example,

<?xml version="1.0" encoding="UTF-8" ?>
<dialog id="commonDialog" bundle="locale.UI" title="idDescription"
modal="true">
  <panel id="pnl_descHead" constraints="BorderLayout.NORTH"
		include="xml/Head.xml#PNL_head"
		bundle="locale.UI1"/>
  <panel id="pnl_descContent" constraints="BorderLayout.CENTER"
		include="xml/Content.xml#PNL_content"
		bundle="locale.UI2"/>
  <panel id="pnl_descFooter" constraints="BorderLayout.SOUTH"
		include="xml/Footer.xml#PNL_Footer"
		bundle="locale.UI3"/>
</dialog>

In above xml, I want to use different bundle properties for each panel.
I tried to specify bundle seperately for each panel, but observed that It
uses locale.UI bundle and not at all using locale.UI1/UI2/UI3.

Can I tell me, where am I wrong OR How can I achieve my goal?
