>
> The link endpoint is destroyed when the link is detached with an error. Such
> link cannot be reattached. Thus, any unsettled deliveries can be safely
> cleared on the link endpoint.
> Clearing of unsettled deliveries should ensure that any undesired disposition
> will not be sent after closing the link as the state carried via such
> disposition should be ignored on peer as per section {{2.7.6 Disposition}} of
> AMQP specification
> {quote}
> The disposition performative MAY refer to deliveries on links that are no
> longer attached.
> As long as the links have not been closed or detached with an error then the
> deliveries are still “live” and the updated state MUST be applied.
> {quote}
> At the moment, the disposition may arrive from errant standard receiving link
> endpoint after its close due to error, when transaction for the delivery is
> discharged (The delivery is settled with null state when transaction is
> rolled back). It does not look right to me to send such disposition, as it
> does not change anything on the peer
