  If libxml2 detects that there is already some text nodes as children of
a node it will disable automatic indenting for the whole subtree.
  Formating is an ad-hoc heuristic, the only way to be 100% sure that
the indenting is correct and non-destructive is to add the indentation
(i.e. the extra text nodes) at the application level. libxml2 should not
guess and will default to the safe side.
