* Interface to provide server unique information used
* during EXCHANGE_ID operation.
* The server scope allows a group of servers to indicate to clients that a set
* of servers sharing the same server scope value has arranged to use compatible
* values of otherwise opaque identifiers. Thus, the identifiers generated by
* one server of that set may be presented to another of that same scope.
* See rfc5661 section 2.10.4 for details.
