Remove header/footer specific views

Hi,

I would like to user Datasource to build complex xml views. I need to nest views within views, done using this module. That would be brilliant, for it would allow to build XML exports based on MarcXML, MODS, Premis...

So I build the first view (the parent view) and build a second (the nested view). I then add the view 2 to view 1. Both built using datasource, hence both produce an xml that has a header, footer and body.

I get an error when nesting the second view. I presume it's due to the fact that the view has a header and therefore disrupts the parent view. How can I exclude the header and footer of a specific view in datasource?
