In XEP-0309, I have a vCard slot for a registration URI:
https://register.jabber.org/
(Yes, it should be "uri", not "url".)
In essence I (as someone running a server directory) would like a way to
capture the server's registration policy in the "contact" vCard. This
helps those who use the directory information (e.g., clients) to do
things like show a drop-down menu of servers that allow an end user to
register in-band (note that support for jabber:iq:register does not
necessarily imply that the server allows in-band registration, since the
server might allow password changes but not registration).
Here's one possible way to do it:
1. If in-band registration is supported, include the XMPP URI of the
server itself:
xmpp:example.com
2. If out-of-band registration is supported, include the appropriate URI
(typically HTTPS):
https://register.example.org/
3. If no registration is supported (e.g., enterprise deployment), don't
include the element.
There might be more elegant ways to do it, but this one seems acceptable
to me. Feedback is welcome. :)
