SVG embedded as <html:img> or <svg:image> *cannot* reference external
resources.  SVG embedded in a document-like way (<object>, <iframe>,
etc.) can.  This is what Robert is trying to say.

Did you not catch that distinction, or are you not aware that external
resources are blocked when SVG is referenced in an "image-like" way?
