  This module converts an XML document into a JSON document.
   - Element ordering is preserved.
   - Attributes and namespaces are ignored.
   - Identical element names become JSON arrays.
  Example usage: 
    let $uri := "somedoc.xml"
    let $doc := fn:doc($uri)
    return jsontools:jsonify($doc)
