Switch has some gnarly options with it, and I do want to find an excuse to use it in my 'SVG embroidery sampler'.
Flags are a possibility, although I only have the UK flag in my SVG sprite sheet thus far.
I will have to see if I can build a usefully stylish locale switcher that gets it right the first time due to browser locale, yet is changeable, with option stored in local storage, all inside the SVG Shadow DOM...
