First, wow! That is amazing!
How does the:
group-by=".//validation/concat(@idref,' == ',(@value,'true')[1])"
work?
I see how the o;?(@value,'true')[1] will select 'true' if no @value
exists, but how does the group-by determine the correct groups? How does
it know there is no value to do the grouping?
thanks,
