-----------------------------------------------------------------
[~jross] what it says is what the authors intended. Note that the set of
outcomes is open, implementers are free to define their own outcomes in
addition to those outlined in the spec, thus a definition along the lines that
[~gsim] proposed above _"any of the outcomes are valid"_ would mean that it is
implicitly saying that it will accept the new outcome
"send_me_helium_filled_elephants" that I have just invented :). I don't intend
to suggest that leaving the outcomes open for extension wasn't a
mistake/confusing, but the definition of supported/default outcome was
specifically crafted to account for these circumstances.

> Key: PROTON-2108
> URL: https://issues.apache.org/jira/browse/PROTON-2108
> Project: Qpid Proton
> Issue Type: Bug
> Affects Versions: proton-c-0.29.0
> Reporter: Robbie Gemmell
> Priority: Critical
>
> From looking at some recent traces, it appears that the bindings (at least
> for python, but probably others) do no set the outcomes (or default-outcome)
> field on its source terminus, although they do use/support all the outcomes.
> To a peer that actually inspects the outcomes to influence behaviour this
> strictly means only Accepted is supported, which can lead to issues (e.g it
> might accept a message then drop it, rather than release/modify/reject it,
> under cases it couldn't be processed).
