---------------------------------------
    Description: 
// Create a Document with a CDATA section that contains an invalid XML character (e.g. 0x1b). 
// This should fail when serializing the Document, but it does not when XMLUni::fgDOMWRTSplitCdataSections is true.

        {

        }
};

typedef std::unique_ptr<XERCES_CPP_NAMESPACE::DOMDocument,XercesDeleter> DOMDocumentPtr;

DOMImplementation* impl = DOMImplementationRegistry::getDOMImplementation(XMLString::transcode("LS"));

 // Create DOM with a CDATA section

DOMElement* element = document->createElementNS(XMLString::transcode("http://schemas.openxmlformats.org/wordprocessingml/2006/main"), XMLString::transcode("w:t"));
document->appendChild(element);

DOMCDATASection* codesection = document->createCDATASection(XercesString("c = '';")); // 0x1B is not a valid XML 1.0 character
element->appendChild(codesection); 

DOMWriterPtr writer(impl->createLSSerializer());

writer->writeToString(document.get())
