Section 5.1 of RFC 3470/BCP 70 includes relevant text. In a nutshell, UTF-8 is a MUST if you're using XML. UTF-16 is recommended since you get it for free with XML parsers, but it's not required. An XML declaration is not needed if you're using either UTF-8 or UTF-16. A byte order mark is required with UTF-16. Other encodings are possible, but if something else is used it must be identified with an appropriate XML declaration. -Scott- _______________________________________________ TLS mailing list TLS@lists.ietf.org https://www1.ietf.org/mailman/listinfo/tls
