Cluster publisher feature in 7.1

Has anyone used this feature? According to the docs,

JMS Cluster Publisher Support JMS Provider 7.1 cluster publisher support now includes failover and load balancing. JMS publishers publish to a list of Broker Servers. If a Broker goes down, the publisher reconnects to one of the other Broker Servers on the list.

There’s not much specifics on how to set this up properly. I’ve set up a couple JMS Connection aliases, but I’m not sure how to refer to them. Doesn’t look like pub.publish:publish has anything new.
