I don't think there is any need to place the burden on Xara with a raw converter. This is better left to dedicated raw conversion software or your image editor of choice, like photoshop, or elements. If you're shooting raw, you're planning on optimizing your image, you will need to use other tools that are not part of, nor should they be of Xara. That being said I think you will be perfectly happy with a high quality jpg.
