I think that the solution with "relevant", suggested earlier, will work 
if Firefox implements correctly "relevant" for <xforms:group>, as well 
as the "instance" attribute on <xforms:submission>. The easiest way to 
make sure would be to give it a try, unless somebody more knowledgeable 
in the Firefox implementation can provide a ready answer.
