Because we convert our SVGs to PNGs before display, we effectively "lose" the translations that be encoded as part of the SVG1.1 spec in the process -- the server just renders everything as though the systemLanguage is English.
We should therefore look to support a "lang=" parameter, for example:
[[File:Foo.svg|thumb|lang=en|English]]
[[File:Foo.svg|thumb|lang=fr|French]]
We can then implement pretty tools for encoding the translations.
