We've been using Sedna XML:DB on Production for about a year as a part of a big product management system based on the xml data model. We're quite happy with this solution although we'd still like to see some more features available (like importing XQuery modules from the local file system resource or from a jar).
Few, realize how powerful and flexible an XML database actually is and Sedna is a strong offering in the category. Its free, fast, and flexible. Many man hours went into this XML and it shows. Good thought went into this document store and it certainly shows aswell.
