I am currently treating each paragraph seperately using panic_languages to back out where no direct translation is available.

You have raised an interesting point in relation to should there be some overall scheme that balences the paragraph readability against document readability. But to do this there has to be a relationship between alternate parts of the text.

The current markup does not show how alternate parts relate but just what language that chunk is in. A better markup would indicate alternate parts and group them together.

Thanks
