XQuery books, tools, and pending new features

While working through the semantics of XQuery, the lack of an update feature was annoying. Though there’s now a candidate XQuery Update Facility as of last Friday. Also, Priscilla Walmsley’s XQuery book alerted me to some differences in the handling of style sheets between XPath 2.0 (used in XQuery) and XPath 1.0 (used in XSLT). By the way, I’d recommend her book if you’re writing XQuery and also oXygen as an XML editor. You can also find some great XQuery examples she’s posted here.
