      * Summary: Provide Canonical XML and Exclusive XML Canonicalization
      * Description: the c14n modules provides a
      *
      * "Canonical XML" implementation
      * http://www.w3.org/TR/xml-c14n
      *
      * and an
      *
      * "Exclusive XML Canonicalization" implementation

      * Canonical form of an XML document could be created if and only if
      *  a) default attributes (if any) are added to all nodes
      *  b) all character and parsed entity references are resolved
      * In order to achive this in libxml2 the document MUST be loaded with
      * following global setings:
      *
      *    xmlLoadExtDtdDefaultValue = XML_DETECT_IDS � XML_COMPLETE_ATTRS;
      *    xmlSubstituteEntitiesDefault(1);
      *
      * or corresponding parser context setting:
      *    xmlParserCtxtPtr ctxt;
      *
      *    ...
      *    ctxt->loadsubset = XML_DETECT_IDS � XML_COMPLETE_ATTRS;
      *    ctxt->replaceEntities = 1;
      *    ...
