    iSCSI: list negotiation description



    First a question again:
    
    What is the point of allowing "inadmissible
    values" (or in case of lists, lack of acceptable
    values) be answered with an "admissible value"?
    
    Now the problems.
    
    Page 69, bottom paragraph:
    
      If a responder does support, understand or
      is allowed to use none of the offered options
      with a specific originator, it MAY use the
      constant "Reject" or it MAY respond with an
      admissible value. The selection of a value
      not offered is considered a negotiation
      failure and is handled as a protocol error.
    
    http://www.pdl.cmu.edu/mailinglists/ips/mail/msg10066.html
    made me believe that the phrase "or it MAY respond
    with an admissible value..." will be removed.
    
    Since it hasn't been, I'll point out again that
    it contradicts the very next sentence, because
    this "admissible value" would be a "value not
    offered".
    Also, I must say that I almost regret having
    started picking on the beginning of this paragraph,
    because IMHO it has gotten worse. I'm still
    proposing this:
    
      If each of the offered values is not understood
      or not supported, or the responder is not allowed
      to use it with the specific originator, it MUST
      use the constant "Reject".
    
    Note that because other reasonable alternatives
    are eliminated, the original "MAY" can change to
    "MUST". (Which should be a good thing, BTW.)
    
    Thanks,
