I belive the intended tool for text output is the xsl transform that can
both re-arrange input nodes (and other DOM modifications which ixml cannot)
and potentially generate any text output. So, I think we should stick to
valid XML in the output which requires a root-node. My bad creating an
invalid grammar. :-)

I expect there to be several ixml+xslt combos developed together, so for
the xmq tool I intend to make it easy to apply such a combo to the input.
