   Hum, I would rather use xmlAddChild(doc, comment) if the root isn't
set yet or if the root is already in place use xmlDocGetRootElement()
and xmlAddPrevSibling(root, comment) .
   xmlDocSetRootElement() is more expected to be used for elements nodes
for example it will wipe out the old root if it already exists.
