Ah, that's awkward, I can see that being needed a lot in different 
circumstances.

In the context I had it, I guess the sequence can be deduced from the 
common nodes, but it would be helpful if there was an order. Having to 
apply a separate role to each way would be OTT, and make it very hard to 
make insertions or deletions.

I'll reword that page for now.
