35 * http://www.w3.org/TR/xml-exc-c14n
36 *
37 * Canonical form of an XML document could be created if and only if
38 * a) default attributes (if any) are added to all nodes
39 * b) all character and parsed entity references are resolved
40 * In order to achieve this in libxml2 the document MUST be loaded with
41 * following global settings:
42 *
43 * xmlLoadExtDtdDefaultValue = XML_DETECT_IDS | XML_COMPLETE_ATTRS;
44 * xmlSubstituteEntitiesDefault(1);
45 *
46 * or corresponding parser context setting:
47 * xmlParserCtxtPtr ctxt;
48 *
49 * ...
50 * ctxt->loadsubset = XML_DETECT_IDS | XML_COMPLETE_ATTRS;
51 * ctxt->replaceEntities = 1;
