XUF Examples

---

DataDirect XQuery bundles several examples that help you understand how to use XUF in your XQuery applications. These examples are located in the \examples\UpdateFacility folder where you install DataDirect XQuery.

These examples, and the XUF expressions and functions they illustrate, are described in the sections that follow this one.
