Subject: [PATCH 1/3] Compatible with "to_xml()" method and ItemId
 initialization method "item_id(std::string id)".
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

    If there is no ChangeKey when initializing item_id, to_xml() returns the data of <t:ItemId Id="AQMkADkzN..." ChangeKey=""/>，which will cause an error.
