Title: Add escape tags flag to config of format

Current to_xml() cannot output the node containing tags.
It is because all nodes are escaped compulsorily.

This feature allows a user to decide whether to escape tags or not.

If $escape_tags is specified false, nodes containing tags will be outputted with CDATA.
