libxml2/parserInternals.h
Daniel Veillard f6eea27b38 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.
