As mentioned earlier, the file type extension for image files is not included in the XML. However, there may be occasions when it is necessary to specify the type of image file that is associated with a given <graphic> element. The Mime Type tag can be used in this case. The following text in the Word file:
Figure 1: This is a figure title<mime>TIFF</mime>
results in the following XML:
<fig id="f1" position="float" fig-type="fig">
<label>Figure 1</label>
<caption><title>This is a figure title</title></caption>
<graphic xlink:href="56789-f04-f1" mimetype="TIFF"/>
</fig>
