+support macros, they have not been ported. However some of them are emulated
+as functions: these are the more useful ones (xmlXPathNodeSetGetLength,
+xmlXPathNodeSetItem, xmlXPathNodeSetIsEmpty, htmlDefaultSubelement,
+htmlElementAllowedHereDesc, htmlRequiredAttrs) and the global/threaded
+variables access macros. These variables can be read with function
