Hi, For about 5 days I have been reading and analyzing the proposal of SVG 1.2. I admire the amount of work and time that you devoted to this project. I wish to comment a few things that are important. The whole project is implementing quite well concepts of artistic graphics for the web. This is OK. However, you missed one large group of users that was hoping to get a good tool in SVG. You missed completely maths and science educators - all levels of all schools and university. What I mean? In educational courseware development we need to define mathematical objects that are given by coordinates and formulae. For example, I wish to create a curve that will be given by equation y=cos(3*x). At the moment there is no easy way to develop such curve in SVG. I would suggest to consider needs of education and make SVG useful for them. Here are some points that are missing in your proposal: 1. declaration of the coordinate system - Cartesian rectangular, polar, etc. 2. declarations of curves given by equations - explicit, implicit, parametric, polar 3. animation by parameter, for example I wish to animate the curve a*x^2 and see what will happen if parameter a will be changing from -5 to 5 4. field of view in Cartesian coordinates, for example I wish to have a coordinate system covering my stage where x=-1..1, and y=-1..5. I guess, there are a few more missing elements that could be useful in developing mathematical courseware in SVG. I would be very happy to work with you in developing this part of the SVG specification. Best regards Mirek Majewski http://www.mathpad.org http://www.mupad.com/majewski/
