[xslt] wrong res->last in resulting document?

Hello, 
  applying the attached stylesheet to the attached document leads
the correct output. However, both from xsltproc and my own application,
from the gdb output below, I can see res->children == res->last, 
but res->children->next != NULL and res->children->next != res->last.

  This implies that if I later call:

    xmlAddChild((xmlNodePtr)res, newnode)

  newnode gets attached right after res->children, replacing
the real res->children->next, which is then lost in memory
and not outputted anymore if I then dump the document.

  I believe the correct res should have res->last=res->children->next 
instead of res->last=res->children.

  This error verifies only if the following conditions are met:
  	method="xml"
	doctype-public=".."
	doctype-system=".."
  if method is not xml, either doctype-public or system are not
set, the result is correct. I couldn't trace the problem
any further. 

libxml: 2.6.11
libxslt: 1.1.8 

I don't have any newer version of libxslt at hand. Sorry if
this bug has already been corrected.

Cheers,
Carlo
