Typing and Querying XML Documents: Some Complexity Bounds

Summary: Systematic complexity study of XML validation and XPath query evaluation on unranked ordered trees under DTDs, XML Schema, and tree automata. Establishes data vs. combined complexity bounds and pinpoints tractable vs. intractable XPath fragments. (summarized by gpt-5-mini on Feb 09 2026)
