[TYPO3] TV: How to create different page templates

 Hy Michael;

  No, that's what I say here:

 Which means you need the whole XML-skeleton around your change:

<T3DataStructure>
    <ROOT type="array">
        <el type="array">
            <field_frame type="array">
                <tx_templavoila type="array">
                    <description>In this little example we change the 
desciption to look different from what has been defined in the 
DS.</description>
                </tx_templavoila>
            </field_frame>
        </el>
    </ROOT>
</T3DataStructure>

It is a bit of work and it may appear redundant, but without the correct 
context the change is sort of ... where?
This is not sufficient:

<description>In this little example we change the desciption to look 
different from what has been defined in the DS.</description>

You know, having 20 fields, which fields description does it change?
Be aware that if you intent to change the <Typoscript>-node that you 
have to give the complete TS-code, not just a "10.sortBy = importance", 
the overlay is not going to disassemble your TS-array.
