// envolope as CDATA. The general schema of this result XML is:

//       <status code = "{code}" message = "{message}">
//   </webcc>
// The "status" node is mandatory, you should define proper status codes and
// messages according to your needs.

//   <webcc type = "result">
//     <status code = "{code}" message = "{message}">
//     <book>
//       <id>{book.id}</id>
//       <title>{book.title}</title>
//       <price>{book.price}</price>
//     </book>
