[TYPO3-templavoila] Adding fields to dataprot XML

[Bill Stoltz]

Is there a hook, or API to allow another extension to edit  the  XML 
(dataprot)  in a TV DS record? Any examples on how  I do that?   I do 
not want to edit this by hand.

One option would be to add new sections like "tx_testing". I have added 
some samples in root and el.field levels in sample XML below.
Another would have items added to existing tx_templavoila like 
"pageModule" info. (example listed below).

Looking for suggestions and best practice on how best to do this..... 

Thanks,
Bill

Sample XML ............

want to be the overall container element for the template.</description>
