Typechecking Top-Down Uniform Unranked Tree Transducersts satisfying a given input schema. As typechecking quickly turns undecidable for query languages capable of testing equality of data values, we return to the limited framework where we abstract XML documents as labeled ordered trees. We focus on simple top-down recursive transformations motivated b

On Reasoning about Structural Equality in XML: A Description Logic Approachn the presence of document type definitions. This application depends on the novel ability of .. to express functional dependencies over sets of possibly infinite feature paths defined by regular languages. We also present a decision procedure for the associated logical implication problem. The proc
