Hi Martin,

Could we simply remove the sentence? The sentence before says pretty much what you suggest, doesn't it?

  "If self-signed certificates are used, the content of the
   subjectAltName attribute inside the certificate MAY use the uniform
   resource identifier (URI) of the user.  This is useful for debugging
   purposes only and is not required to bind the certificate to one of
   the communication endpoints.  The integrity of the certificate is
   ensured through the fingerprint attribute in the SDP."

Regards,

Christer
