[ccnet-user] CleanUp tag - how to get it working for multitype SVN-sourcecontrol ?

[VC]

Hi all,
  Due to some constraints I had to configure the 2 folder-checkout for
building one installer and hence the below. How ever I couldn't get
the automatic cleanUp working as am getting a msg saying :
"Service cannot be started.
ThoughtWorks.CruiseControl.Core.Config.ConfigurationException: Unused
node detected: <cleanUp>True</cleanUp>"

To-be-fixed-config-block is as below...

<project>...
......
<sourcecontrol type="multi" >
     <cleanUp>True</cleanUp> <!--I do not know if this works for multi-
type-sourcecontrol-->
      <sourceControls autoGetSource="true">
        <svn>
         <!--Placing the cleanUp tag here too failed with same error
msg as above-->
          <executable>svn.exe</executable>
          <trunkUrl><trunkurlhere></trunkUrl>
          <tagOnSuccess>false</tagOnSuccess>
                  <cb:logincredentials/>
          <workingDirectory>C:\WD\lib</workingDirectory>
          <autoGetSource>true</autoGetSource>
        </svn>
        <svn>
          <executable>svn.exe</executable>
          <trunkUrl><trunkurlhere></trunkUrl>
          <tagOnSuccess>false</tagOnSuccess>
                                             <cb:logincredentials/>
          <workingDirectory>C:\WD\virdir</workingDirectory>
          <autoGetSource>true</autoGetSource>
        </svn>
     </sourceControls>
    </sourcecontrol>
........
</project>...

Appreciate, if any of you could share your suggestions on getting this
to work ?

Note- Please accept my apologies as I posted similar message into
another post-thread and realized later the need for a wider-attention
to get more suggestions/recommendations.

Thanks
