  Some whitespace text nodes if the stylesheet asks for for strip-space
on some elements. 
      if (xsltNeedElemSpaceHandling(ctxt))
              xsltApplyStripSpaces(ctxt, xmlDocGetRootElement(doc));
  The _private field will be modified too for elements which are keys

I think that's all. If I suggested to copy it's for a reason !
Don't forget to read the documentation on the internals if you start 
doing this kind of tricks:
