URI on Image is not working correctly. It is not possible to reference ID's on external resources. Example: <svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"> <image xlink:href="https://dvcs.w3.org/hg/FXTF/raw-file/tip/filters/images/shader-concept.svg#image" width="558" height="378" /> </svg> It is not displayed with WebKit.
