>>> co = etree.Element("county", name="Socorro")
>>> st.append(co)
>>> etree.tostring(st)
'<state name="New Mexico"><county name="Socorro"/></state>'
>>> rem = etree.Comment("Just another day in paradise.")
>>> st.append(rem)
>>> etree.tostring(st)
'<state name="New Mexico"><county name="Socorro"/><!-- Just another day in
paradise. --></state>'
