 Section 5.2.6 (TLS Extensions) states:

 > Because XMPP services are often provided in so-called virtual
 > hosting deployments, it is RECOMMENDED for the initiating entity
 > to include an extension of type "server_name" as defined in
 > [TLS-EXT].  If an XMPP service hosts multiple domains on the same
 > IP address, it MUST enable support for the "server_name" extension.

 Matthew Wild commented: "Says that servers MUST support the server_name
 extension, however it doesn't give much information on how it would be
 used. It seems only useful in the context of 5223, which has never been
 standardized. Perhaps drop this requirement? Or at least reduce it to
 MAY."

 Dave Cridland commented: "Mandating server_name? This seems
 unsatisfactory, not least because XMPP has its own perfectly sound method
 for selecting server name which works perfectly well."
