Tutorials need to be written based on final documents. For XML Query, you'll find some good examples in the Use Cases document. XML Query seems to me to have been improving steadily over the past two years or so, and in particular is now much more closely aligned with the way W3C XML Schema types and validation work. I should probably add that this doesn't preclude something like relax-ng validation in a future version -- only the basic type system is wired in, and if you're going to have a type system, it does seem to make some sense to build it on other type systems in use with XML. People here complaining about Schema support should note that it's optional: the Basic Conformance Level of XML Query doesn't require it. Users also don't have to worry about it. If you want to get the benefits (colour all links red, and all headings blue, find me all dates between these ranges used in changelog entries and make an RSS feed, find all elements derived from CorporateTypes-phoneNumber and check they don't contain our old telephone numberextensange prefix), then you'll be glad of the new features.
