Message : Bugfixes, extesion and optimizations for XSLT: - xpath.c: removed an error found by XSLT usage - tree.c parserInternals.h: use a predefined static string for text and comment nodes, avoid freeing them in xmlFreeNode, exported the string name in parserInternals.h and added another value to disable encoding at output (for XSLT), gain memory, time.
