  I don't now, all I can tell, is that if you have a default namespace
in scope (xmlns="...") then those xmlSetProp'ed attributes won't inherit
the namespace, get the namespace first and then use xmlSetNsProp()
  That would generate a difference in behaviour between the serialized
and reparsed tree vs. using the tree directly
