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
   "&#00FC;" 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 &#00FC; 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&#00FCss@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.
