By "the error occurs" do you mean that an exception is thrown? Or does
the thread complete without any errors but the written XML is incomplete?

What happens if you disable your calculation code (i.e., just parse XML
into the object model and then write this object model back to XML without
any modifications)?

If none of this makes any difference, then the next step would be to
determine whether this is an XSD problems or a Xerces-C++ problem by
removing XSD from the equation. Right now, when you call an XSD-generated
parsing function, it first parses XML to DOM and then parses DOM to the
object model. Similarly, when you call the serialization function, it
first creates DOM from the object model and then serializes DOM to XML.
The idea is to just do: XML->DOM->XML. Will you be able to modify your
code to do this? You can find ready-to-use functions for DOM parsing and
serialization in the 'messaging' example (see the dom-{parse,serialize}.?xx
files).
