-@cindex draft changes to output syntax of @sc{gdb/mi}
-@cindex @sc{gdb/mi}, draft changes to output syntax
-
-One problem identified in the existing @sc{gdb/mi} output syntax was the
-difficulty in differentiating between a tuple such as:
-
-@example
-@{number="1",type="breakpoint",disp="keep",enabled="y"@}
-@end example
-
-where each value has a unique label, and a list such as:
-
-@example
-@{"1","2","4"@}
-@{bp="1",bp="2",bp="4"@}
-@end example
-
-where values are un-labeled or the label is duplicated.
-
-What follows is a draft revision to the output specification that
-addresses this problem.
-
-The output from @sc{gdb/mi} consists of zero or more out-of-band records
-optionally followed by a single result record, the result record being
-for the most recent command input. The sequence is terminated by
-@samp{(@value{GDBP})}.
-
-Asynchronous @sc{gdb/mi} output is similar.
-
-Each output record directly associated with an input command is prefixed
-by the input command's @code{@var{token}}.

-The @code{@var{token}} is from the corresponding request. If an execution
-command is interrupted by the @code{-exec-interrupt} command, the token
-associated with the `*stopped' message is the one of the original
-execution command, not the one of the interrupt command.

-@var{status-async-output} contains on-going status information about the
-progress of a slow operation. It can be discarded. All status output is
-prefixed by the prefix @samp{+}.

-@var{exec-async-output} contains asynchronous state change on the target
-(stopped, started, disappeared). All async output is prefixed by
-the prefix @samp{*}.

-@var{notify-async-output} contains supplementary information that the
-client should handle (new breakpoint information). All notify output is
-prefixed by the prefix @samp{=}.

-@var{console-stream-output} is output that should be displayed as is, in the
