Hi Andrei, I'm the author of the saxon wrapper library at https://github.com/pjt/saxon. User-defined XPath functions are indeed desirable but I haven't done anything special in the library to help in implementing them.
What's available by default in Saxon is the ability to call Java methods. For static methods, you associate a namespace in the XSLT document with a class in Java, as in "nav" below: <xsl:stylesheet version="2.0" xmlns:nav="java:net.sf.saxon.om.Navigator" xmlns:xsl="http:// www.w3.org/1999/XSL/Transform"> Then you can call static methods of that class as if it were an XPath function, e.g. <xsl:value-of select="nav:getPath(.)"> Combine this with Clojure's class-generation facility (http:// clojure.org/compilation) & you can pretty easily see how to go about writing Clojure extension functions. This isn't as convenient as one could imagine, but it's a way to do it right now.
