I want to include an inline svg in an html5 page that includes \"use\" tags that reference elements in a different svg file, referenced by URL. This is part of the SVG spec
svg4everybody uses requestAnimationFrame, which causes too many calls. I wrote a simple and lighweight polyfill for the very purpose of supporting elements with external references when the browser itself fails. This polyfill uses feature detection rather than browser sniffing. It's on github: https://github.com/Keyamoon/svgxuse
