*
* 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;
* ...
