Hi, I have reviewed the property path tests. We need tests for {m,n}, {,n}, ? and () for precedence, and I think we need more tests for combinations of property path constructs. I have disagreements with some of the answers given in the current tests. 1) pp15 -- I don't see why we are returning results on an empty dataset. 2) pp16 -- I don't understand why the path d --> e --> f --> e is included. 3) pp25 -- I don't understand why the path a --> c --> c is included. For pp16 and pp25, these paths repeat a node (i.e. contain a cycle). I thought we were using a node marking algorithm to prevent cycles. Thanks, Matt
