I just saw a tweet which demonstrates that the STOMP spec still needs more clarification. I think Brian McCallister, the founding architect of protocol, will agree that one of the tenets of the protocol was for it to be simple enough to even use by user which directly connects to a server via telnet.

And to support that use case, newlines after the frame terminator are a natural occurrence. But it might be easier to describe it as:

• A stomp frame may have zero or more newlines preceding it’s command verb.
