XML with Incomplete Information: Models, Properties, and Query Answering
Summary: Classifies XML incomplete-information models (nulls + partial structure) and frames key tasks: consistency, representability, and query-answering. Characterizes how schemas, node IDs, and structural gaps affect complexity and isolates fragments with tractable query evaluation. (summarized by gpt-5-mini on Feb 09 2026)
