Is this hiding some content from some users? Or not displaying the content at all to anyone?
For the former, we implemented a Javascript widget (added to xforms.js) which worked out whether to display an element as read-only or writable based on the user - something like this could be done to completely hide the information if the document already exists.
Of course, if the information is in the XML, there's nothing stopping the user opening up the XML document directly in their browser and viewing the information that way.
