Linux-libre is a project to maintain and publish 100% Free distributions of Linux, suitable for use in Free System Distributions, removing software that is included without source code, with obfuscated or obscured source code, under non-Free Software licenses, that do not permit you to change the software so that it does what you wish, and that induces or requires you to install additional pieces of non-Free Software.
Recently Linux-Libre has been formally accepted as an official part of the GNU Project. The first release of Linux-libre since its dubbing as a GNU package is now available from the download links off of http://linux-libre.fsfla.org/"

In other words, this group of developers has been attempting to implement SVG since the W3C started developing it, and hasn't succeeded yet.
Actually, our SVG implementation is almost complete, only lacking a few things. I believe that the most important and substantial thing that we still do not support are the animation tags. As Inkscape is nowadays a drawing application (not an animation app yet), then I think it is not reasonable to say that we haven't succeeded in SVG implementation yet. We have solid support for the subset of SVG features that are needed for a drawing app. And this subset is substantially large.
You can expect to see animation support in some future version, and then we'll probably see an Inkscape 1.0 later, when the standard finally gets fully implemented.
