Either is ok with me as long as the description lines up with how the
PropertyDescriptor is configured. Just a little odd to claim that it's optional
and then make it required :)

> Key: NIFI-865
> URL: https://issues.apache.org/jira/browse/NIFI-865
> Project: Apache NiFi
> Issue Type: Wish
> Components: Extensions
> Reporter: Joseph Witt
> Assignee: Oleg Zhurakousky
> Labels: beginner
> Fix For: 0.5.0
>
>
> David Smith in the mailing list has already begun work on this. The link to
> his current set of code in Github is here:
> https://github.com/helicopterman22/nifi_amqp_processors
> He is seeking help with licensing/unit testing/etc.. so that it can end up in
> a build.
> We have word from another user now that they too are interested in this.
> They specifically are using RabbitMQ but we should be able to implement
> (ideally) a pure AMQP protocol friendly version and be good to go.
