I think the Internationalization best practice currently suggests not
putting all languages in the same file; furthermore this approach won't
work if e.g. you have Japanese or Chinese with "ruby" annotations, or if
for some other reason you need markup or formatting in the content.

You can use element() from gcpm with :lang and that may form a better
example, I'm not sure. The two-argument element() isn't widely
implemented, so you end up with extra copies of text in your document,
but this is likely to be better than having document content in CSS,
especially for accessibility.
