Working with SVG in a RWD workflow usually involves a design phase and a development phase. The design phase is usually handled by designers who may or may not know how to code. And because of the nature of SVG as both an image format and a document format, every step taken in the graphics editor in the process of creating the SVG directly affects the resulting code and hence the work of the developer in charge of embedding, scripting or animating the SVG. In my day-to-day work, I am usually the developer whom designers hand the design assets over to, and SVG images are part of those assets.
