[TYPO3-templavoila] Change TS template in different TV template objects

[Uwe]

I have a TemplaVoila problem

I want to change my TypoScript-Template in case I use another 
TemplaVoila Template Object for a page. I found the field "local 
processing (xml)" in the Template Object dataset. How do I use this 
field for this?

I found the following code, but it does not work, nothing changed:
<T3DataStructure>
  <ROOT>
   <el>
    <field_content>
     <tx_templavoila>
      <TypoScript>
# Seiten-Optionen
lib.siteOptions = COA
lib.siteOptions {
     10 = TEXT
     10.value = Drucken
     10.wrap = <a href="drucken.html"><img 
src="fileadmin/templates/images/quadratbl.gif" alt="Blaues Quadrat" 
width="8" height="6" border="0">|</a>&nbsp;&nbsp;
     20 = TEXT
     20.value = Per EMail verschicken
     20.wrap = <a href="mail.html"><img 
src="fileadmin/templates/images/quadratbl.gif" alt="Blaues Quadrat" 
width="8" height="6" border="0">|</a>&nbsp;&nbsp;
     30 = TEXT
     30.value = Autor kontaktieren
     30.wrap = <a href="kontakt.html"><img 
src="fileadmin/templates/images/quadratbl.gif" alt="Blaues Quadrat" 
width="8" height="6" border="0">|</a>
}
      </TypoScript>
     </tx_templavoila>
    </field_content>
   </el>
  </ROOT>
</T3DataStructure>

I cannot use the Data Structure, because I have only one data structure 
for all templates.

Thanks!
