> This JIRA refers to Proton(-C) only.    Analogous work was already carried out for Proton-J under PROTON-1486.
> The Proton Engine API provides no mechanism for getting or setting the additional-data field on sasl-outcome.
> Some SASL mechanisms (e.g. SCRAM-SHA-\*) send additional data along with the outcome (in the case of SCRAM-SHA-\* the additional data is a proof that the server is also aware of the credentials and is not simply just accepting any credential data as part of some sort of attack).
> One approach for the API would be to expose the additional-data field using the send/recv/pending methods used for exchanging the challenge/response in the earlier phases of the sasl exchange.
