Subject: [MMUSIC] POF/PAN: New stream with port zero forbidden?

Hi,

In section 5.3, the first sub-bullet of bullet 3 (new stream) says:

          "If the received media section contains a port number of zero,
          then the recipient MUST reject the partial offer as invalid
          behavior: this mechanism does not support the atomic addition
          and removal of the same stream."

Now, while I can't think of a use-case why anyone would send a POF with port zero (for a new stream), what is the reason for forbidding it?

Regards,

Christer
