Interaction between Path and Type Constraints
Summary: Characterizes implication problems for path constraints (inclusions/inverses) over semistructured XML with and without schema/type systems, targeting semantics and query-optimization applications. Proves that types can both lower complexity (undecidable→cubic-time and finitely axiomatizable) and raise it (PTIME→undecidable) for different implication problems.
