Hello Alex, Please apologize our late reply on this question. We discussed this issue recently and propose to return path.getPointAtLength(0) for negative values and path.getPointAtLength(path.getTotalLength()) for values that are bigger than the total path length. It is proposed that "out of range" values don't result in error reporting. One of the reasoning is that sometimes there might be accuracy issues with path length calculations from potentially different sources or algorithms. We will provide an errata for SVG 1.1 Full and include it in SVG 1.2 Full. Does that sound reasonable from an implementers point of view?
