[zeromq-dev] PUB/SUB guarantee on message order

I am trying to find some reference to the guarantees zeroMQ gives when receiving data via PUB/SUB. The guide says that basically zeroMQ tries hard to deliver messages, but they may get lost. If a message is received, it is complete. Now, I am interested in guarantees on the order of messages. When I send messages from PUB to SUB, is it guaranteed that if they arrive, that will be in sending order? I have not found any official statement in the protocols or in the guide, and searching the internet has not shown a real consensus.

It would be nice if somebody could point to a document or other source.
