 Of course $system.xlists is more difficult. Perhaps instead something
 like $system.xlistnames could be an N-element array of K_i-element 
 arrays of strings with the names of the regressors in the i=1..N 
 equations. (So an array inside an array inside a bundle, if that doesn't 
 scare you.) 
Wait, an array inside an array isn't possible in hansl I guess... So it 
somehow would have to be an array of bundles or something.
I know we have the special "list of lists" construct in system 
definitions - don't know how that could be stuffed in the $system 
bundle, though. Hm.
