captiontag is only used to provide a caption for a figure, subfigure, or a table. You can enter a somewhat lengthy description of the figure with the
captiontag. In contrast, using the title tag you can enter only a brief title or label that appears above a figure.
<figure id="fig1"> <media id="dog-pic" alt="A dog sitting on a bed"> <image mime-type="image/jpeg" src="image1.jpg"/> </media> <caption> This dog is sitting, unlike some dogs. </caption> </figure>
