In my working copy I now have:


The <enabled/> element MAY include a 'location' attribute to specify the
receiving entity's preferred IP address or hostname (optionally with a
port) for reconnection, in the form specified in Section of
rfc3920bis [9] (i.e., "domainpart:port", where IPv6 addresses are
enclosed in square brackets "[...]" as described in RFC 5952 [10]); if
reconnection to that location fails, the standard XMPP connection
algorithm specified in XMPP Core [11] applies.


I've also added a bit more text to the section on resumption...


As noted, the <enabled/> element MAY include a 'location' attribute that
specifies the server's preferred location for reconnecting (e.g., a
particular connection manager that hold session state for the connected

Example 9. Server prefers reconnection at a particular location

S: <enabled xmlns='urn:xmpp:sm:3'

If the stream is terminated unexpectedly, the initiating entity would
then open a TCP connection to the receiving entity. The order of events
is as follows:

   1. After disconnection, the initiating entity opens a new TCP
connection to the receiving entity, preferring the address specified in
the 'location' attribute (if any).
