Very much so, brilliant! But what about concept maps, the suggestion is 
to use proxy objects but won't that be very cumbersome? Aren't concept 
maps important enough?

btw. I think it does more than cover necessary ground, with CTFE 
constraints are more powerful, though that may have limited use.
