The formatting elements used in a definition are subsets of formatting collections described above.

A dxf record is referenced by zero-based index, meaning the numerical order in which the dxf appears under dxfs.

<dxfs count="1">
  <dxf>
    <font>
      <b/>
      <color theme="0"/>
    </font>
    <fill>
      <patternFill patternType="solid">
        <fgColor theme="5"/>
        <bgColor theme="5"/>
      </patternFill>
    </fill>
  </dxf>
