                Add text along the lines suggested by David - "include 
                a note in the spec saying that if someone combines 
                multiple schema languages may be a problem, and we 
                have not solved this problem."

  Media Type Description Note
    Issue 272: Architectural issues
      RESOLUTION: Closed - no interest in pursuing a NOTATION based
                  solution.
      ACTION: Umit to add a warning along the lines of:
        "The intent of the expectedMediaType attribute is to allow WSDL 
        authors to indicate the range of media types that are acceptable

        for the binary data for which it is defined for, hence it serves

        as an design time indicator for possible contentType values that

        are expected. Therefore, authors are recommended to use wild 
        cards with care, and recommended to indicate the list of media 
        types if the set is limited."
      RESOLUTION: accept 2a, 2b, 3 from Addison's email
      ACTION: media type editors to rename xmlmime: to xmime
