We show some published results on chasing tree pattern queries using schema constraints for tree pattern containment test are incorrect.

Introduction. XPath plays a central role in all XML query lan- guages. A major fragment of XPath can be rep- resented as tree patterns [3].

We first provide an example to show that two previously published results in [2] and [4] on tree pattern containment under schema graphs are incorrect.

We present two sets of chase rules to chase a tree pattern repeatedly, and compare the advantages of these chase rules. References. [1].
