My guess was;
  Libxml always dumps attribute values with " (double-quote) enclosure,
  so there's no need to encode ' as '.

But libxml encodes " to " and does not encode ' to '
even while dumping the text node content.
For readability, I think it is better not to encode single/double-quote
character to the entity string while dumping the text content.
