The W3C XSL Working Group has published the requirements for the XSL Formatting Objects 2.0. "A number of XSL 1.0 implementations already support dynamic inclusion of vector graphics using W3C SVG. The XSL and SVG WGs want to define a tighter interface between XSL-FO and SVG to provide enhanced functionality. Experiments with the use of SVG paths to create non-rectangular text regions, or 'run-arounds', have helped to motivate further work on deeper integration of SVG graphics inside XSL-FO documents, and to work with the SVG WG on specifying the meaning of XSL-FO markup inside SVG graphics. A similar level of integration with MathML is contemplated."
