It doesn't.

Some challenges to be met though.

If you make schematics == SVG files, you need to ensure that opening and
saving from an SVG editor (e.g. Inkscape) won't break the data within.

Gschem currently uses special primitives to mark connectivity - nets,
pins, buses etc.. I'm not quite clear how that can be mapped to SVG in a
way which doesn't loose that information when edited outside of the EDA
tool.

Perhaps 2x way is too much to hope for though.. and we can just rely on
the fact our files will render as an SVG. XCircuit does this with
postscript files.

Btw - I have a branch lurking about which emits SVG onto the clipboard
when copy+pasting within gschem. That lets you paste from gschem
straight into Inkscape. The net and pin end-cues aren't quite right with
it though.
