Added info to Group header in BI xml output

We have a need to output data in XML format.  I would like to use xml publisher.  This data is not going into an RTF document.  It will be XML output.  I have the first pass working well getting out what I need but I have a need to add info the group tag.  The tag should look like this:

<csvBeginWTPart handler="wt.part.LoadPart.beginCreateWTPart" >

Is this possible in the xml written for the data definition?

<dataStructure>

<group name="csvBeginWTPart"             dataType="varchar2"     source="NmLoader">  ...

</group>

</dataStructure>

Thanks in advance,
