The IESG has received a request from the SIP-TO-XMPP WG (stox) to

Addresses, and Error Handling'
<draft-ietf-stox-core-07.txt> as Proposed Standard
A small nit - §5.5 contains:
Several examples follow, illustrating steps 3, 5, and 8 described
above (the percent-encoded string "%C3%BC" and XML Notation string
"�FC;" both represent the Unicode character LATIN SMALL LETTER U
WITH DIAERESIS).
I don't think this is quite true. The percent-encoded string is an encoding of the codepoint U+FC as UTF-8, whereas the construct �FC; is an XML notation for the character - which crucially is not part of the address format, but simple how one could transmit the address over XML (including XMPP).
The example given is actually tsch�FCss@xmpp.example - due to there being no terminating ";", I'd expect that to be taken literally by an XML parser, and not be treated as tschüss@xmpp.example as I suspect is desired.
