Hello, because such a circle path segment seems not to be connected to the segments before and after, I think, the usage for general paths is limited. New/simpler commands to be able to draw circular and elliptical arcs have already been discussed - including one of my proposals to enable authors in general to provide path data in polar coordinates. Another proposal cares about simpler notations for objects with discrete rotation symmetry, sometimes called 'star'. Because it is not trivial to provide general parameters to integrate elliptical arcs into arbitrary path, I think the current complexity of the commands A and a result more or less from the requirement of generality. Because there are already commands like H and V to note specific straight lines, a simple method to be able to draw a circular segment would fit to the current command collection, but one has to ensure, that initial and final points of such a segment get automatically connected to possible other segments before and after this one. Another feature already in discussion is one that enables authors to join elements together to one object - or to substract objects from another collection of objects to get for example shapes with holes more easily - currently for example for SVG tiny it is an advanced task to create a shape with a round hole with a small number of path segments ;o) But of course, the WG members have to comment, what they really want to add to SVG 2 to enable authors to write more semantic code with limited file size. Because an element called circle has much more semantical meaning than arbitrary path data, this should not be deprecated. And to be able to note features of known objects separately is pretty useful for authors of animations to animate each feature independently from the others. Olaf
