Put in your XQuery String in the text box and hit submit. This is 'raw' XQuery meaning you need to declare
your own namespaces (if needed). There is nothing given to you on the xquery by the server. You may elect to use
the special reserver word 'RootResource' to be translated to the root node hence vr:Resource or vor:Resource.
Once you hit submit it takes you to an XML page of your results, you will need to hit back button to get back to the menu or XQuery page.
