Use of SVG in XDA Web Exports

[Acorn]

Dear Xara...

I want to maintain the highest presentational quality in my websites. With the improvements to your Xara HTML filter over the years, we now have boxes marked up as HTML DIV tags rather than raster images.

Can you go a little further? The XDA chooses the best raster file format from JPEG and PNG, which can be overruled by the designed in Web Properties > Image > Web image type.
Can you also now include the vector SVG format as a further choice?

I appreciate not all browsers handle SVG; your built-in Internet Explorer previewer being a case in point.
I currently set a suitable graphic to PNG and give it a Name, filename="<image>". I then export the graphic by copying it into a Blank Photo template (this has to change!) as <image>.svg.
I set the original image Link to file to <image>.svg. finally, I add Placeholder code:

<object type="image/svg+xml" data="index_htm_files/<image>.svg">
<img src="index_htm_files/<image>.png" />
</object>

This allows for a fallback to PNG if the SVG cannot be rendered. I still need to keep a copy of the PNG on the page so I usually soft-group it behind the Placeholder.

I would like all this to be automated within the Xara HTML filter.

Thanks.
