- * 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 achieve this in libxml2 the document MUST be loaded with
- * following global settings:
- *
- *    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;
