 * http://www.w3.org/TR/xml-exc-c14n
 *
 * 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;
