It's specified in ZMTP 3.0 but not implemented in libzmq yet.

My advice is to step back from what you want to make, and instead
spend a few days learning the 0MQ patterns and semantics by working
through the Guide. When it "clicks" for you, go back to your problem
and make a simple minimal design. Then develop that little by little.
If you try to make the real architecture directly, it will usually not
work due to the many wrong assumptions you have about how 0MQ works,
and you'll be disappointed with 0MQ.
