\$doc is a reference to an XML::Writer::_String object instead of a reference to a scalar,

Well, it's both, seeing as $doc is a scalar. And furthermore, the contents of the scalar are obviously meant to be used as a string (If not, $doc would be given a reference.) So don't be afraid to use it as a string.
