XTABLES: Bridging relational technology and XML

Additional work completed after the publication of "XTABLES: Bridging relational technology and XML" (IBM Systems Journal 41, No. 4, 2002) indicated that a number of figures containing XQUERY and XML commands in that paper require modifications or additions in order to be correct and complete. We present the modified figures and other queries, along with SQL commands that can be used to generate the sample data described in the original paper and those produced by the modified queries.
