As discussed with NikcDC, this will be useful, for instance for the SVG export to know the mime type of the linked file. If not PNG, JPG or SVG, we may want to output a small warning that some viewers may not be able to read such files, since the SVG spec makes the support of these 3 formats only as mandatory.
