That is correct. Each message exchanged in BEEP is formatted with MIME. MIME specifies that the headers and body are separated by CRLF. The fact that there are no headers must be indicated by terminating the headers. > Which is then terminated by CRLF.

Note that the second thru last frame of a complete message does not need to have MIME headers, so indeed the payload of a frame is just *OCTET. That the message is structured according to the rules of MIME implies that headers are separated from body by CRLF, even if there are no headers.
