We have translated the uberAgent dashboard app (written in Simple XML) to German. While doing so we found that:
Inline HTML elements cannot be localized.
HTML can only be localized when loaded from a file, e.g.: <html src="update_inventory_explanation.html"></html>. Provide one file per target language, e.g. for German: update_inventory_explanation-de.html
Localizing content that comes from JavaScript seems to be possible, but we have not tried it yet.
