Comment 2 for bug 1659347

Please note that the core of the report focuses on the value in the xlink:href attribute. The sodipodi:absref attribute in the custom namespace in my understanding mostly matters on the local platform of the author (absolute links to files on a local hard drive rarely work on other systems). A relative image link in the xlink:href attribute on the other hand is not only used by Inkscape (not restricted to a private namespace used by Inkscape), and AFAIU should not use a OS-specific path separator.
