Store of XML documents on Hybrid Schema differs from version

To store a XML document in a Hybrid Schema (Tamino version 3) the XML must contain an empty element to the mapped element (if not, on queries the mapped element does not appear). With Tamino version 2 it is not necessary.

How is the better way to work (load XML documents)?
