[7] XFA Date and Time Formats xfa-datetime という文書があったらしいが、 Internet Archive にも所蔵なし。 2021-04-21T03:45:35.200Z

[8] https://web.archive.org/web/20000819135454/http://www.xfa.com/spec/xfa-template-19990504/#ref-xfa-datetime 時点で 「@@tbd」となっていて、 https://web.archive.org/web/20000819135434/http://www.xfa.com/spec/xfa-template-19990614/#ref-xfa-datetime では 「"XFA Date and Time Formats", G. McKenzie, R. McDougall, February 1998. Available at http://www.xfa.com/spec/xfa-datetime.html」 となっている。一応存在はしたのだろう。
