I find doing multi-level grouping is far easier using variables instead of 
using keys if you don't need a node set at the end of your grouping.

Please find a running example below where I store in variables only those 
in the scope of being grouped, and then use generate-id() with that 
variable to find the unique members.

I didn't

I hope this helps.
