<schema>
  <sequence | choice
      name
      output='yes'
      min-occur='0'
      max-occur='1'>

      <record
          name
          output='yes'
          record-sep
          min-occur=0
          max-occur=1>

          <field
                name
                output='yes'
                field-sep

                default-value
                leading-chars
                trailing-chars
                max-length='128'
