It would be helpful to know how those developing bilingual sites are creating a language toggle as on standard gov't pages. If you're on the English page, you should see a link to the French page and vice-versa.
In Drupal 7 I'm using the core language switcher block of the locale module. However that displays a link to the current active language as well as to the translated language, and doesn't seem to be configurable. I'm not sure if I can override it somehow?
I've come across this solution for Drupal 6, which seems pretty hefty for such a small issue:

Alternately, at the bottom of the content there are links to translated pages. Perhaps this output could separated out and displayed in the theme region of my choosing?
Your comments would REALLY be helpful!
