# Message Ruby methods
module WMQ
  # Message contains the message descriptor (MQMD), data
  # and any headers.
  #
  # Note:
  # * The format in the descriptor applies only to the format of the data portion,
  #   not the format of any included headers
  # * The message format can ONLY be supplied in the descriptor.
  #   * I.e. It is the format of the data, Not the headers.
  #   * On the wire formats are determined automatically by the :header_type key for
  #     each header
  #   * Other WebSphere MQ interfaces require that the formats be "daisy-chained"
  #     * I.e. The MQMD.Format is actually the format of the first header
  #     * Ruby WMQ removes this tedious requirement and performs this
  #       requirement automatically under the covers
  #   * The format of any header should not be supplied in the descriptor or any header
  #
  # Message has the following attributes:
  # * descriptor = {
  #                                                           # WebSphere MQ Equivalent
  #     :format             => WMQ::MQFMT_STRING,             # MQMD.Format - Format of data only
