Orbeon Forms: Extracting Form Summary Data

We create a "summary section" at the top of one of our forms to display the main form data. To do this we used an Explanatory Text control along with many Template Parameters to extract the data from other controls (either directly or via xPath). This works fine..

However, when we came to extract the form data into another reporting tool (via API) we realised that the API only brings over data with a value e.g. text box, radio-button checkbox etc, and NOT the Explanatory Text..

So, here is the question.

We need to put this "summary" data in either a Plain/Formatted text box instead, but you can't use Template Parameters in these control in the same way as Explanatory Texts.

We tried using xPath to move the data from one control to the other, but that didn't work.

So what is the best way to address this?
