What kind of JSON data structure does SDL WorldServer Translation expect?

I need to output a json file that is translated by WorldServer, but no one seems to know how I should format the json.  It's currently in XML.



<line>text from line 1</line>

<line>text from line 2</line>


How would I format that in JSON?

I tried it as an array..

{ "text": ['text from line1', 'text from line2'] }

But they said that doesn't work.

I can't find documentation for this...  Can anyone help?
