  that's wrong. You just generate a broken tree, and even when 
serializing that should not work as < would be escaped.

  include/libxml/tree.h
xmlNodePtr XMLCALL xmlNewCDataBlock(xmlDocPtr doc, const xmlChar *content, int len);

  If you use the search engine on xmlsoft.org selecting the XML API and
lookup for CData it's show up on the 12th line:

   http://xmlsoft.org/search.php?query=CData&scope=XMLAPI

"10 xmlNewCDataBlock function tree Creation of a new node containing a CDATA block"
