Can make a working minimal example. As you use xml as input language it’s no problem to save some settings and apply them later to each cell which will allow you to set different values for the frames.

You should also know that each xtable cell is a framed (it uses the \framed code) like natural tables and \setupxtable accepts the same arguments as \setupframed.

I’m sorry but I was wrong, the “spaceinbetween” value isn’t passed to \blank but context expects here something like “spaceinbetween={\vskip <dimension>}”. I can send a patch to Hans because a internal blank would be allow you to write “spaceinbetween=1cm” or “spaceinbetween=2*line”.
