   >>> from lxml.etree import Element, tostring

   >>> a = Element("{foo}a", nsmap={None:"foo"})
   >>> a.append(Element("{bar}b", nsmap={None:"bar"}))

   >>> print tostring(a, pretty_print=True)
   <a xmlns="foo">
     <b xmlns="bar"/>
   </a>


This is on lxml 2.0 alpha, lxml 1.3 should work alike.
