  I would separate both APIs

  xmlNewTextWriterDoc() would return a new xmlDocPtr

  xmlNewTextWriterTree() would take a doc and an existing node within that
doc, and add any new elements as last child of the given node. It should IMHO
return the first element added that way. The only danger is to be careful
about text node coalescing done by libxml2 if adding text sibling to existing
text nodes.
