It appears to be probably unintentional-but-ok: libxml tags a CDATA
section differently (XML_CDATA_SECTION_NODE) than a text node
(XML_TEXT_NODE), so a CDATA node falls into the catch-all branch of
if (cur->type != XML_ATTRIBUTE_NODE && cur->type != XML_TEXT_NODE)
where it gets dumped faithfully by xmlNodeDump(), with the upshot
that the result always will be well-formed XML, and will respect whether
the input was supplied as CDATA or not. We could choose to say that's
what we meant it to do all along.
