Do you need to worry about the delimeter here? Just using:
concat(../@name, @name)
should be fine for the grouping key
This obviously creates the (probably small) risk that ("AB", "C") ends up in
the same group as ("A", "BC").
ahh, good point. That explains Ken's reasoning for choosing a
separator that's not contained in the values eg:
"A-", "B"
and
"A", "-B"
would give the same key "A--B" if the separator was a dash - what a
gotcha that would be :)
