Mapframe maps are internationalized, and have two new parameters: lang="xx" and lang="local". The maps users get when they click on maplink links should have these same behaviors and capabilities. E.g., one should be able to put the following on a page:
<maplink zoom=9 latitude=37.8013 longitude=-122.3988 lang="ja"></maplink>
And the map that pops up when users click on the link created should be in Japanese.
