XQuery from the Experts Errata

This page contains updated information on the Addison-Wesley publication, XQuery from the Experts: A Guide to the W3C XML Query Language. It lists typos that have been discovered in the book, as well as (as soon as I get around to it!) changes which have been made to the XQuery specification since the book was published in September, 2003. The book was written collaboratively by the following members of the W3C Query Working Group: Don Chamberlin Denise Draper Mary Fernandez Michael Kay Jonathan Robie Michael Rys Jerome Simeon Jim Tivy, and Phil Wadler

The double quote following the last entry, currency should be a period.
